7.1
Port 0 is an 8-bit input port. Port 0 pins also function as A/D converter analog input pins and
EXIRQ input pins.
Port 0 has the following register.
• Port 0 register (PORT0)
7.1.1
PORT0 is an 8-bit read-only register, that reflects the pin state in port 0. PORT0 cannot be
modified.
Note:
7.1.2
If the corresponding bit in PTCNT1 is set to 1, the port 0 pins can be used as interrupt input pins
(ExIRQ7 to ExIRQ4).
Pin function relationships are listed below.
Note: When these pins are set as the interrupt input pins, do not use them as the A/D converter
