programmable MOS input pull-ups and LED
driving capability. The direction of each bit
can be selected in the port 2 data direction
register (P2DDR).
P3₇ to P3₀ 89 to 82
I/O Port 3: An 8-bit input/output port with
programmable MOS input pull-ups. The
direction of each bit can be selected in the
port 3 data direction register (P3DDR).
P4₇ to P4₀ 56 to 49
I/O Port 4: An 8-bit input/output port. The
direction of each bit can be selected in the
port 4 data direction register (P4DDR).
