Port AD1 general purpose input/output data—Data Register

This register is associated with ATD1 analog inputs AN[7:0] on PAD[23:16], respectively.

When not used with the alternative function, these pins can be used as general purpose I/O.

If the associated data direction bits of these pins are set to 1, a read returns the value of the port register, otherwise

the buffered pin input state is read.

Port AD1 data direction—

This register controls the data direction of pins 15 through 8.

1 Associated pin is conﬁgured as output.

0 Associated pin is conﬁgured as input.

Port AD1 Data Register 1 (PT1AD1)

Port AD1 Data Direction Register 0 (DDR0AD1)
