Signals and Connections
Table 3. MC9328MXL Signal Descriptions (Continued)
Function/Notes
SPI2 Slave SelectâThis 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 ClockâThis 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.
General Purpose Timers
Timer Input Capture or Timer Input ClockâThe signal on this input is applied to both timers
simultaneously.

Secure Digital Interface
SD CommandâIf the system designer does not wish to make use of the internal pull-up, via the Pull-
up enable register, a 4.7Kâ69K external pull up resistor must be added.
MMC Output Clock
DataâIf the system designer does not wish to make use of the internal pull-up, via the Pull-up enable
register, a 50Kâ69K external pull up resistor must be added.
Memory Stick Interface
