I/O ports
P0_0 to P0_7
P1_0 to P1_7
P2_0 to P2_7
P3_0 to P3_7
P4_0 to P4_7
P5_0 to P5_7
I/O
VCC2
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
resistor may be enabled or disabled for input ports in 4-bit
units.
P6_0 to P6_7
P7_0 to P7_7
P8_0 to P8_7
P9_0 to P9_7
P10_0 to P10_7
I/O
VCC1
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.
No pull-up resistor is provided. P8_5 is an input port for
verifying the
NMI
pin level and shares a pin with
NMI
.
