8.11. Target Board Pin Assignment Summary
Some GPIO pins of the C8051F338 MCU can have an alternate fixed function. For example, pin 22 on the 'F338
MCU is designated P0.4, and can be used as a GPIO pin. Also, if the UART0 peripheral on the MCU is enabled
using the crossbar registers, the TX signal is routed to this pin. This is shown in the "Alternate Fixed Function"
column. The "Target Board Function" column shows that this pin is used as TX on the 'F338 Target Board. The
"Relevant Headers" column shows that this signal is routed to pin 7 of the J1 header and pin 5 of the J3 header.
More details can be found in the C8051F336/7/8/9 data sheet. Some of the GPIO pins of the C8051F338 have
been used for various functions on the target board. Table 6 summarizes the MCU pin assignments on the target
board, and also shows the various headers associated with each signal.
*Note: Headers denoted by this symbol are not directly connected to the MCU pin; the connection might be via one or more
