Port Integration Module (S12GPIMV0)
2.5
2.5.1
Each pin except BKGD can act as general-purpose I/O. In addition most pins can act as an output or input
of a peripheral module.
2.5.2
A set of configuration registers is common to all ports with exception of the ADC port
registers can be written at any time, however a specific configuration might not become active.
Example: Selecting a pullup device. This device does not become active while the port is used as a
push-pull output.

PIM Ports - Functional Description
1
Port AD interrupt flag—
If the associated interrupt enable bit is set this flag asserts after a valid active edge was detected on the related pin
(see
polarity select register.
Writing a logic “1” to the corresponding bit field clears the flag.
1 Active edge on the associated bit has occurred (an interrupt will occur if the associated enable bit is set)
0 No active edge occurred
