18. I/O Ports
Bit 2n + 1 (n = 0–15)—Port Pull-Up Control (PBnPUP): Specifies whether each bit in the 16-
bit port A is to be pulled up with a built-in resistor. Pull-up is automatically turned off for a port
pin set to output by bit PBnIO.

Bit 2n (n = 0–15)—Port I/O Control (PBnIO): Specifies whether each bit in the 16-bit port A is
an input or an output.

18.2.2
Port data register A (PDTRA) is a 16-bit readable/writable register used as a data latch for each bit
in the 16-bit port A. When a bit is set as an output, the value written to the PDTRA register is
output from the external pin. When a value is read from the PDTRA register while a bit is set as an
input, the external pin value sampled on the external bus clock is read. When a bit is set as an
output, the value written to the PDTRA register is read.
PDTRA is not initialized by a power-on or manual reset, or in standby mode, and retains its
contents.
