Chapter 24 DG128 Port Integration Module (S12XDG128PIMV2)
24.0.5.61 Port AD1 Data Direction Register 1 (DDR1AD1)
Read: Anytime.
Write: Anytime.
This register configures pins PAD[7:0] as either input or output.
24.0.5.62 Port AD1 Reduced Drive Register 0 (RDR0AD1)
Read: Anytime.
Write: Anytime.
This register configures the drive strength of each PAD[15:8] output pin as either full or reduced. If the
port is used as input this bit is ignored.
