4.1. System Clock Sources
The C8051F300 device installed on the target board features a calibrated programmable internal oscillator which is
enabled as the system clock source on reset. After reset, the internal oscillator operates at a frequency of
3.0625 MHz (+/-2%) by default but may be configured by software to operate at other frequencies. Therefore, in
many applications an external oscillator is not required. However, if you wish to operate the C8051F300 device at a
frequency not available with the internal oscillator, an external crystal may be used. Refer to the C8051F30x data
sheet for more information on configuring the system clock source.
The target board is designed to facilitate the installation of an external crystal. Remove resistors R7 and R8 and
install the crystal at the pads marked Y1. Install a 10 M resistor at R9 and install capacitors at C14 and C15 using
values appropriate for the crystal you select. Refer to the C8051F30x data sheet for more information on the use of
external oscillators.
4.2. Switches and LEDs
Two switches are provided on the target board. Switch SW1 is connected to the RESET pin of the C8051F300.
Pressing SW1 puts the device into its hardware-reset state. Switch SW2 is connected to the C8051F300’s general
purpose I/O (GPIO) pin through headers. Pressing SW2 generates a logic low signal on the port pin. Remove the
shorting block from the header to disconnect SW2 from the port pins. The port pin signal is also routed to a pin on
the J1 I/O connector. See Table 1 for the port pins and headers corresponding to each switch.
Two LEDs are also provided on the target board. The red LED labeled PWR is used to indicate a power connection
to the target board. The green LED labeled with a port pin name is connected to the C8051F300’s GPIO pin
through headers. Remove the shorting block from the header to disconnect the LED from the port pin. The port pin
signal is also routed to a pin on the J1 I/O connector. See Table 1 for the port pins and headers corresponding to
each LED.

4.7. Low-Pass Filter (J7)
The C8051F300 target board features a low-pass filter that may be connected to port pin P0.6. Install a shorting
block on J7[1-2] to connect the P0.6 pin of the target device to the low-pass filter input. The output of the low-pass
filter is routed to the PWM signal at J1[2]. The C8051F300 may be programmed to generate a PWM (Pulse-Width
Modulated) waveform which is then input to the low-pass filter to implement a user-controlled PWM digital-to-analog converter. Refer to Applications Note “AN107: Implementing 16-Bit PWM Using the PCA” in the “documentation” directory on the CD-ROM for a discussion on generating a programmable dc voltage level with a PWM
