2. When the P10/ANI0 to P17/ANI7 pins are used as the analog inputs for A/D converter, set port 1 to input
(FRC) to 1, and be sure not to use the feedback resistor of the subsystem clock oscillation circuit.
mode. The on-chip pull-up resistors are automatically disabled.
For pins which also function as port pins, do not perform the following operations during A/D
conversion. If these operations are performed, the total error ratings cannot be kept.
<1> Rewrite the output latch while the pin is used as a port pin.
<2> Change the output level of the pin used as an output pin, even if it is not used as a port pin.

Port 1
8-bit input/output port
Input/output is specifiable bit-wise.
When used as the input port, it is possible to
use an on-chip pull-up resistor by software.
Port 2
8-bit input/output port
Input/output is specifiable bit-wise.
When used as the input port, it is possible to
use an on-chip pull-up resistor by software.
Port 3
8-bit input/output port
Input/output is specifiable bit-wise.
When used as the input port, it is possible to
use an on-chip pull-up resistor by software.
