Regardless of the operating mode of the shared
pin, reading or test is always possible.
Can be set in the input or output bit-wise.
Can be set in the input or output mode as a 4-
bit unit. Ports 4 and 5, 6 and 7, and 8 and 9 are
paired and data input/output is possible as an
8-bit unit.
Can be set to input or output mode as a 4-bit
unit. Ports 12 and 13 are paired and data input/
output is possible as an 8-bit unit.
These pins are shared with SI,
SO, SCK, INT0 to INT4.
Port 2, PT00, PT01, and PCL share
the same pins.
On-chip pull-up resistor specifi-
able bit-wise by mask option.
*
Can drive a LED directly.
