Chapter 24 DG128 Port Integration Module (S12XDG128PIMV2)
24.0.5.65 Port AD1 Pull Up Enable Register 1 (PER1AD1)
Read: Anytime.
Write: Anytime.
This register activates a pull-up device on the respective PAD[7:0] pin if the port is used as input. This bit
has no effect if the port is used as output. Out of reset no pull-up device is enabled.
Functional Description
Each pin except PE0, PE1, and BKGD can act as general purpose I/O. In addition each pin can act as an
output from the external bus interface module or a peripheral module or an input to the external bus
interface module or a peripheral module.
A set of configuration registers is common to all ports with exceptions in the expanded bus interface and
ATD ports
not become active.
This device does not become active while the port is used as a push-pull output.
