SPI2 Master TxData Output—This signal is multiplexed with a GPI/O pin yet shows up as a primary or
alternative signal in the signal multiplex scheme table. Please refer to the SPI and GPIO chapters in
the MC9328MX1 Reference Manual for information about how to bring this signal to the assigned pin.
SPI2 Master RxData Input—This signal is multiplexed with a GPI/O pin yet shows up as a primary or
alternative signal in the signal multiplex scheme table. Please refer to the SPI and GPIO chapters in
the MC9328MX1 Reference Manual for information about how to bring this signal to the assigned pin.
SPI2 Slave Select—This signal is multiplexed with a GPI/O pin yet shows up as a primary or alternative
signal in the signal multiplex scheme table. Please refer to the SPI and GPIO chapters in the
MC9328MX1 Reference Manual for information about how to bring this signal to the assigned pin.
SPI2 Serial Clock—This signal is multiplexed with a GPI/O pin yet shows up as a primary or alternative
signal in the signal multiplex scheme table. Please refer to the SPI and GPIO chapters in the
MC9328MX1 Reference Manual for information about how to bring this signal to the assigned pin.
General Purpose Timers
Timer Input Capture or Timer Input Clock—The signal on this input is applied to both timers
simultaneously.
