6612_OMU_S2+2_URT_V1_14 Firmware Description Document
1 Introduction
This document describes the firmware 6612_OMU_S2+2_URT_V1_14, which can be used with the
Teridian 78M6612 power and energy measurement IC. This firmware provides simple methods for
calibration, relay control, and access to measurement data such as Watts, Voltage, Current, accumulated
Energy and line frequency. It is optimized for measurement of up to two single phase AC loads using
current shunts as the current sensors, but Current Transformer (CT) sensors may also be used if desired.
All measurement calculations are computed by the 78M6612 and communicated to the host processor
over a serial interface (UART0) on the TX and RX pins of the 78M6612 device. RTC (real time clock),
LCD Driver, and Battery Modes are not supported by this firmware. Additional 78M6612 hardware
utilized by this firmware includes:
•
•
•
•
DIO20 used as a configurable status alarm output pin
DIO4, DIO5, and DIO8 as LED outputs for Active, Ready, and Fault status
DIO7 and DIO19 used as configurable relay control ouputs
DIO6 used as an optional pulse output
The following sections detail the commands to be sent by the host to configure the 78M6612 and for
accessing measurement information.
2 Description of Basic Measurement Equations
The Teridian 78M6612 with firmware 6612_OMU_S2+2_URT_V1_14 provides the user with two types of
continuously updating measurement data (on 1 second increments by default). One is defined as
“Narrowband” (NB) and the other is defined as “Wideband” (WB).
Narrowband measurements are typically used by utilities where the measured waveforms are
assumed to be sinusoidal.
Wideband measurements are generally of interest when measuring nonlinear systems such as
switched mode power supplies that tend to have non-sinusoidal waveforms. This firmware
utilizes an effective sampling rate of 3641 samples per second.
Table 1 lists the basic measurement equations for the Narrowband and the Wideband methods.

3 Serial Communication
The serial communication with the 78M6612 takes place over a UART (UART0) interface. The default
settings for the UART of the 78M6612, as implemented in this firmware, are given below:
Baud Rate:
Data Bits:
Parity:
Stop Bits:
Flow Control:
38400bps

Xon/Xoff
The host’s serial interface port is required to implement these settings on its UART. To verify
communication between the host and the 78M6612, the host must send a (carriage return) to the
78M6612. Communication is verified when the 78M6612 returns a > (greater than sign) known as the
command prompt. An example is given below:
The host sends the following to the 78M6612:
The 78M6612 sends the following back to the host:
>
Commands the host may send to the 78M6612 in order for the host to configure the 78M6612 or to
receive the measurement data are given in the next section.

4 Command Line Interface
Firmware 6612_OMU_S2+2_URT_V1_14 implements an instruction set called the Command Line
Interface (CLI), which facilitates communication via UART between the 78M6612 and the host processor.
The CLI provides a set of commands which are used by the host to configure and to obtain information
from the 78M6612.
4.1
Identification and Information Commands
The I command is used to identify the revisions of Demo Code and the contained CE code. The host
sends the I command to the 78M6612 as follows:
>I
The 78M6612 will send back to the host the following:
TSC 78M6612 OMU S2+2 URT v1.14, Feb 09 2010(c)2009 Teridian Semiconductor Corp.

4.2
Reset Commands
A soft reset of the 78M6612 can be performed by using the Z command. The soft reset restarts code
execution at addr 0000 but does not alter flash contents. To issue a soft reset to the 78M6612, the host
sends the following:
>Z
The W command acts like a hardware reset. The energy accumulators in XRAM will retain their values.
Z

UG_6612_017
MPU Data Access Command
The most pertinent is the MPU data access command. All the measurement calculations are stored in the
MPU data addresses of the 78M6612. The host requests measurement information using the MPU data
access command which is a right parenthesis
)
To request information, the host sends the MPU data access command, the address (in hex) which is
requested, the format in which the data is desired (Hex or Decimal) and a carriage return. The contents
of the addresses that would be requested by the host are contained in Section 5.
4.3.1 Individual Address Read
The host can request the information in hex or decimal format. $ requests information in hex, and ?
requests information in decimal. When requesting information in decimal, the data is preceded by a + or
a -. The exception is )AB? which returns a string (see the AB description).
An example of a command requesting the measured power in Watts from Outlet 1 (located at address
0x08) in decimal is as follows:
>)08?
An example of a command requesting the measured power in Watts from Outlet 1 (located at address
0x08) in hex is as follows:
>)08$
4.3.2 Consecutive Read
The host can request information from consecutive addresses by adding additional ? for decimal or
additional $ for hex.
An example of requests for the contents in decimal of ten consecutive addresses starting with 0x12 is:
>)12??????????
An example of requests for the contents in hex of ten consecutive addresses starting with 0x12 would be:
>)12$$$$$$$$$$
Note: The number of characters per line is limited to no more than 60.

4.3.3 Block Reads
The block read command can also be used to read consecutive registers: )saddr:eaddr? For decimal
format or )saddr:eaddr$ for hex format where saddr is the start address and eaddr is the final address.
The following block read command requests the Outlet 1 wideband information contained in Table 4 in
decimal format:
>)20:3D?
4.3.4 Concatenated Reads
Multiple commands can also be added on a single line. Requesting information in decimal from two
locations and the block command from above are given below:
>)12?)15?)20:3D?

Calibration Commands
Using the precision source method, the user provides a precision voltage and precision current load to
the device for calibration. The 6612_OMU_S2+2_URT_V1_14 firmware provides commands to calibrate
the measurement units. For linear current sensors, such as current shunt, no phase calibration is
necessary.
There are two types of calibration commands. The first type provides complete calibration. The second
group, called atomic calibration commands, provides calibration for individual portions of the IC.
4.5.1 Complete Calibration Command (“Single Command Calibration”)
There are two calibration commands in this first group: CAL and CALW. Only one of these commands
is needed to calibrate the System/Unit.
To use these commands, a precision voltage source and a precision current source are required
4.5.1.1 CAL Command
To use the CAL command, enter the following:
>CAL
The response is:
TCal OK
VCal OK
ICal 0 OK
>
The device would calibrate the temperature (reads CE register 71, enters it into MPU register C0, and
saves to flash), calibrate the voltage (adjusts CAL VA and CAL VB registers and saves them to flash),
and finally calibrate the current (adjusts CAL IA register and saves to flash).

I/O RAM (Configuration RAM) Command
The RI command is used for altering the I/O RAM contents. This is usually not necessary as the FW
defaults these settings appropriately.
One case where the RI command could be used would be to change the accumulation interval for energy
measurements. The default accumulation interval is 1 second (999.75 ms). The accumulation interval is
set by the following:
0.01666 * SUM_CYCLES[5:0] (in seconds) where SUM_CYCLE[5:0] are register bits in the I/O
RAM that can be between 15d and 63d (default is 60d). SUM_CYCLES must never be set below
15 (0.250 seconds).
To reduce the accumulation interval to 0.5 seconds, enter the following via the UART:
RI1=+30
Entering a U command will preserve the new accumulation value across power resets, by writing them to
flash.
R
I/O RAM Control
Description:
Allows the user to read from and write to I/O RAM.
Usage:
RI {option} {register} … {option}
Command
Combinations:
RIx…
Select I/O RAM location x (0x2000 offset is
automatically added).
Example:
RI60$$$$
Read all four RTM probe registers.
Configuration RAM space is the address range 0x2000 to 0x20FF. This RAM contains
registers used for configuring basic hardware and functional properties of the 78M6612
and is organized in bytes (8 bits). The 0x2000 offset is automatically added when the
command RI is typed.
