The V850/SA1 includes 85 I/O port pins configuring ports 0 to 12 (13 ports are input only).
There are three power supplies for the I/O buffers; AV
Port 0 is an 8-bit I/O port for which I/O settings can be controlled in 1-bit units. A pull-up resistor can be connected
When P00 to P04 are used as the NMI and INTP0 to INTP3 pins, noise is eliminated from these pins by an analog
When P05 to P07 are used as the INTP4/ADTRG, INTP5/RTPTRG, and INTP6 pins, noise is eliminated from these

When port 0 (P0) is read, the pin levels at that time are read. Writing to P0
writes the values to that register. This does not affect the input pins.
When port 0 (P0) is read, the P0 values are read. Writing to P0
writes the values to that register, and those values are immediately output.
