7.10. Target Board Pin Assignment Summary
Some GPIO pins of the C8051F800 MCU can have an alternate fixed function. For example, pin 17on the
C8051F800-GM 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 C8051F800
Target Board. The "Relevant Headers" column shows that this signal is routed to pin 15 of the J1 header and pin 12
of the J3 header. More details can be found in the C8051F80x-83x data sheet. Some of the GPIO pins of the
C8051F800 have been used for various functions on the target board. Table 5 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
