23.0.5.67 Port AD1 Data Register 1 (PT1AD1)
Read: Anytime.
Write: Anytime.
This register is associated with AD1 pins PAD[15:8]. These pins can also be used as general
purpose I/O.
If the data direction bits of the associated I/O pins are set to 1, a read returns the value of the port
register, otherwise the value at the pins is read.
23.0.5.68 Port AD1 Data Direction Register 0 (DDR0AD1)
Read: Anytime.
Write: Anytime.
This register configures pin PAD[23:16] as either input or output.
