8-bit CMOS I/O ports. A direction register determines whether
each pin is used as an input port or an output port. A pull-up
I/O
VCC2
resistor may be enabled or disabled for input ports in 4-bit
units.
8-bit I/O ports having equivalent functions to P0. However,
P7_0, P7_1, and P8_5 are N-channel open drain output ports.
I/O
VCC1
No pull-up resistor is provided. P8_5 is an input port for
verifying the NMI pin level and shares a pin with NMI .
