C8051F326/7-DK
6.6. Target Board DEBUG Interface (J4)
The DEBUG connector (J4) provides access to the DEBUG (C2) pins of the C8051F326. It is used to connect the
Serial Adapter or the USB Debug Adapter to the target board for in-circuit debugging and Flash programming.
Table 4 shows the DEBUG pin definitions.
6.7. Serial Interface (J5)
A RS232 transceiver circuit and DB-9 (J5) connector are provided on the target board to facilitate serial connec-
tions to UART0 of the C8051F326. 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.
6.8. 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.

J3[9–10] - Install shorting block to connect UART0 TX (P0.4) to the transceiver.
J3[11–12] - Install shorting block to connect UART0 RX (P0.5) to the transceiver.
J3[13–14] - Install shorting block to connect UART0 RTS (P2.4) to the transceiver.
J3[15–16] - Install shorting block to connect UART0 CTS (P2.5) to the transceiver.
