Register Map Page
Figure 8 shows the registers map page. All the registers are available on this page. When "Auto Read" is
set to other than "Off", all the registers will be read automatically and periodically according to the interval
time the user selects. Otherwise the user will need to click "READ REGISTER" to read the selected
register or to click "READ ALL REGISTERS" to read all registers.
Clicking on the row of a register automatically updates the corresponding field view on the right side of the
page. The register value can be updated by modifying the hexadecimal value in the "Value" column or by
double-clicking the corresponding bit in the "Bits" column. The modified value is effective immediately if
"Immediate Write" is selected. When "Deferred Write" is selected, the modified value won't take effect until
the user clicks "WRITE REGISTER" button. All registers' value can be updated together by clicking
"WRITE ALL REGISTERS".

Instructions for Standalone Evaluation
The LP8866EVM can be used for standalone evaluation (without GUI software and PC connection). To
support standalone mode, it must be modified from its default settings as described below:
1. Mount R20 to pull up EN input.
2. Change pullup and pulldown resistors to select spread spectrum enable (R18) or disable (R25) option.
3. Mount R19 to pull up PWM input for 100% brightness. If brightness needs to be changed from 100%,
connect external PWM source at PWM pin.
The minimum procedures for turning on the LEDs after modifications above are as follows:
1. Connect a 12-V external power supply between the power input terminals VBAT+ and GNDin on the
LP8866EVM.
2. Connect LP886X-LEDLAOD-EVM board (6 strings, 8 LEDs per string) to J10 on the LP8866EVM.
3. Turn on the external power supply.

LED Load Board
An LED load board LP886X-LEDLOAD-EVM is included in the EVM kit. The LED board is intended to be
used as the load for LED driver and can be configured for up to 6 strings and up to 20 LEDs in the string
(Number of LEDs in use is defined by jumpers). The initial setting on the board is 8 LEDs in series per
string. Cree XLamp ML-C LEDs with maximum current of 350 mA (for parallel use) and maximum forward
voltage of 3.4 V at 100 mA (3.2-V typical) are used on the board.

STANDARD TERMS FOR EVALUATION MODULES
1.
Delivery: TI delivers TI evaluation boards, kits, or modules, including any accompanying demonstration software, components, and/or
documentation which may be provided together or separately (collectively, an “EVM” or “EVMs”) to the User (“User”) in accordance
with the terms set forth herein. User's acceptance of the EVM is expressly subject to the following terms.
1.1 EVMs are intended solely for product or software developers for use in a research and development setting to facilitate feasibility
evaluation, experimentation, or scientific analysis of TI semiconductors products. EVMs have no direct function and are not
finished products. EVMs shall not be directly or indirectly assembled as a part or subassembly in any finished product. For
clarification, any software or software tools provided with the EVM (“Software”) shall not be subject to the terms and conditions
set forth herein but rather shall be subject to the applicable terms that accompany such Software
1.2 EVMs are not intended for consumer or household use. EVMs may not be sold, sublicensed, leased, rented, loaned, assigned,
or otherwise distributed for commercial purposes by Users, in whole or in part, or used in any finished product or production
system.
2
Limited Warranty and Related Remedies/Disclaimers:
2.1 These terms do not apply to Software. The warranty, if any, for Software is covered in the applicable Software License
Agreement.
2.2 TI warrants that the TI EVM will conform to TI's published specifications for ninety (90) days after the date TI delivers such EVM
to User. Notwithstanding the foregoing, TI shall not be liable for a nonconforming EVM if (a) the nonconformity was caused by
neglect, misuse or mistreatment by an entity other than TI, including improper installation or testing, or for any EVMs that have
been altered or modified in any way by an entity other than TI, (b) the nonconformity resulted from User's design, specifications
or instructions for such EVMs or improper system design, or (c) User has not paid on time. Testing and other quality control
techniques are used to the extent TI deems necessary. TI does not test all parameters of each EVM.
