24.0.5.63 Port AD1 Reduced Drive Register 1 (RDR1AD1)
Read: Anytime.
Write: Anytime.
This register configures the drive strength of each PAD[7:0] output pin as either full or reduced. If
the port is used as input this bit is ignored.
24.0.5.64 Port AD1 Pull Up Enable Register 0 (PER0AD1)
Read: Anytime.
Write: Anytime.
This register activates a pull-up device on the respective PAD[15:8] 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.
