This table concerns Full-featured version. Please refer to “SPC56xP54/60 device configuration difference” table for

difference between Full-featured, and Airbag configuration.

ALT0 is the primary (default) function for each port after reset.

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

PCR[PA] = 00

 ALT0; PCR[PA] = 01  ALT1; PCR[PA] = 10  ALT2; PCR[PA] = 11  ALT3. This is intended to select

the output functions; to use one of the input-only 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 “—”.

Module included on the MCU.

Multiple inputs are routed to all respective modules internally. The input of some modules must be configured by setting the

values of the PSMI[PADSELx] bitfields inside the SIUL module.

Programmable via the SRC (Slew Rate Control) bits in the respective Pad Configuration Register.

LQFP176 available only as development package.

Weak pull down during reset.
