Port 4
Input
AD0 to AD7
8-bit I/O port.
Input/output can be specified in 8-bit units.
When used as an input port, a pull-up resistor can be specified by means
of software.
The test input flag (KRIF) is set to 1 by falling edge detection.
Notes 1. When using the P07/XT1 pin as an input port, set bit 6 (FRC) of the processor clock control register (PCC)
to 1. Do not use the on-chip feedback resistor of the subsystem clock oscillator.
2. When using the P10/ANI0 to P17/ANI7 pins as A/D converter analog input pins, set port 1 to the input mode.
At this time, pull-up resistors are automatically disconnected.
