Port Integration Module
PERM[7:0] — Pull Device Enable Port M
1 = Either a pull-up or pull-down device is enabled.
0 = Pull-up or pull-down device is disabled.
Port M Polarity
Select Register
(PPSM)
Read: Anytime.
Write: Anytime.
This register selects whether a pull-down or a pull-up device is
connected to the pin. If CAN is active a pull-up device can be activated
on the RxCAN[3:0] inputs, but not a pull-down. If BDLC is active a
pull-down device can be activated on the RxBDLC pin but not a pull-up.
PPSM[7:0] — Pull Select Port M
1 = A pull-down device is connected to the associated port M pin,
if enabled by the associated bit in register PERM and if the port
is used as a general purpose or BDLC input but not as RxCAN.
0 = A pull-up device is connected to the associated port M pin, if
enabled by the associated bit in register PERM and if the port
is used as general purpose or RxCAN input but not as BDLC.
