The following pad types are available for system pins and functional port pins

Port

Alternate functions are chosen by setting the values of the PCR[PA] bitfields inside the SIUL module.

PCR[PA] = 00 selects Option 0

PCR[PA] = 01 selects Option 1

PCR[PA] = 10 selects Option 2

PCR[PA] = 11 selects Option 3

This is intended to select the output functions. To use one of the input functions, the PCR[IBE] bit must be written to ‘1’, regardless of the values selected in

the PCR[PA] bitfields. For this reason, the value corresponding to an input only function is reported as “—”.

Special functions are enabled independently from the standard digital pin functions. Enabling standard I/O functions in the PCR registers may interfere with

their functionality. ADC functions are enabled using the PCR[APC] bit; other functions are enabled by enabling the respective module.

Using the PSMI registers in the System Integration Unit Lite (SIUL), different pads can be multiplexed to the same peripheral input. Please see the SIUL chapter

of the MPC5645S Microcontroller Reference Manual for details.

See the “Pad types” section for an explanation of the letters in this column.

Reset configuration is given as I/O direction and pull, e.g., “Input, pullup”.

Out of reset pins PH[0:3] are available as JTAG pins (TCK, TDI, TDO and TMS respectively). It is up to the user to configure pins PH[0:3] when needed.
