Signals and Connections
SPI2_TXD
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 MC9328MXL Reference Manual for information about how
to bring this signal to the assigned pin.
SPI2_RXD
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 MC9328MXL Reference Manual for information about how to
bring this signal to the assigned pin.
SPI2_SS
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_SCLK
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.

SD_CMD
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.
SD_CLK
MMC Output Clock
SD_DAT [3:0]
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 Interface
MS_BS
Memory Stick Bus State (Output)—Serial bus control signal
MS_SDIO
Memory Stick Serial Data (Input/Output)
MS_SCLKO
Memory Stick Serial Clock (Input)—Serial protocol clock source for SCLK Divider
