22.3.2.64 Port AD0 Reduced Drive Register 1 (RDR1AD0)
Read: Anytime.
Write: Anytime.
This register configures the drive strength of each output pin PAD[07:00] as either full or reduced. If the
port is used as input this bit is ignored.
22.3.2.65 Port AD0 Pull Up Enable Register 1 (PER1AD0)
Read: Anytime.
Write: Anytime.
This register activates a pull-up device on the respective pin PAD[07:00] if the port is used as input. This
bit has no effect if the port is used as output. Out of reset no pull device is enabled.
