7.14. Target Board Pin Assignment Summary
Some GPIO pins of the C8051F540 MCU can have an alternate fixed function. For example, pin 30 on the
C8051F540 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 C8051F540 Target
Board. The "Relevant Headers" column shows that this signal is routed to pin 6 of the J14 header and pin 6 of the
J1 header. More details can be found in the C8051F54x data sheet. Some of the GPIO pins of the C8051F540
have been used for various functions on the target board. Table 9 summarizes the C8051F540 MCU (Side A) pin
assignments on the target board, and also shows the various headers associated with each signal.
