Port Integration Module (PIM9E256V1)
3.1
The port integration module establishes the interface between the peripheral modules and the I/O pins for
for ports AD, M, P, Q, S, T and U.
This section covers:
Each I/O pin can be configured by several registers: input/output selection, drive strength reduction, enable
and select of pull resistors, wired-OR mode selection, interrupt enable, and/or status flags.
3.1.1
A standard port has the following minimum features:
