Input for an external A/D trigger.
Extended analog input for the A/D converter.
Output for the D/A converter.
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. P8_5 is an N-channel open drain
output port. No pull-up resistor is provided. P8_5 is an
input port for verifying the NMI pin level and shares a pin
with NMI.
VCC1
I/O ports having equivalent functions to P0. However,
P7_0 and P7_1 are N-channel open drain output ports.
No pull-up resistor is provided.
Note:
1. TXD2, SDA2, and SCL2 are N-channel open drain output pins. TXDi (i = 0, 1, 5), SDAi, and SCLi can be
selected as CMOS output pins or N-channel open drain output pins.
