C8051F32x
4.6. Target Board DEBUG Interface (J4)
The DEBUG connector (J4) provides access to the DEBUG (C2) pins of the C8051F320. It is used to connect the
Serial Adapter or the USB Debug Adapter to the target board for in-circuit debugging and Flash programming.

4.7. Serial Interface (J5)
A RS232 transceiver circuit and DB-9 (J5) connector are provided on the target board to facilitate serial
connections to UART0 of the C8051F320. The TX, RX, RTS and CTS signals of UART0 may be connected to the
DB-9 connector and transceiver by installing shorting blocks on header J3.
J3[9-10]- Install shorting block to connect UART0 TX (P0.4) to transceiver.
J3[11-12]- Install shorting block to connect UART0 RX (P0.5) to transceiver.
J3[13-14]- Install shorting block to connect UART0 RTS (P2.6) to transceiver.
J3[15-16]- Install shorting block to connect UART0 CTS (P2.7) to transceiver.
4.8. Analog I/O (J6)
Several of the C8051F320 target device’s port pins are connected to the J6 terminal block. Refer to Table 5 for the
J6 terminal block connections.

4.9. USB Debug Adapter Target Board Power Connector (J8)
The USB Debug Adapter includes a connection to provide power to the target board. This connection is routed
from J4[10] to J8[1]. Place a shorting block at header J8[2-3] to power the board directly from an ac/dc power
adapter. Place a shorting block at header J8[1-2] to power the board from the USB Debug Adapter. Please note
that the second option is not supported with either the EC1 or EC2 Serial Adapters.
4.10. Low-Pass Filter (J7)
The C8051F320 target board features a low-pass filter that may be connected to port pin P2.4. Install a shorting
block on J7[1-2] to connect the P2.4 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 C8051F320 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 for a discussion
on generating a programmable dc voltage level with a PWM waveform and low-pass filter.
