Signal Name
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 MC9328MXL 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 MC9328MXL Reference Manual for information about how to bring this signal to the assigned
pin.
Timer Input Capture or Timer Input Clock—The signal on this input is applied to both timers
simultaneously.

USB Analog Front End Enable
SD Command—If the system designer does not wish to make use of the internal pull-up, via the Pull-
up enable register, a 4.7K–69K external pull up resistor must be added.
MMC Output Clock
Data—If the system designer does not wish to make use of the internal pull-up, via the Pull-up enable
register, a 50K–69K external pull up resistor must be added.
Memory Stick Bus State (Output)—Serial bus control signal
Memory Stick Serial Data (Input/Output)
Memory Stick Serial Clock (Input)—Serial protocol clock source for SCLK Divider
Memory Stick External Clock (Output)—Test clock input pin for SCLK divider. This pin is only for test
purposes, not for use in application mode.
General purpose Input0—Can be used for Memory Stick Insertion/Extraction detect
General purpose Input1—Can be used for Memory Stick Insertion/Extraction detect
