I/O Port Map and Allocation

When an I/O extension board is not used, I/O port numbers (the number specified when I/O is processed with PAC program or I/O command) go up to 511. However, when an I/O extension board (option)is used, I/O port numbers beyond 511 are added.

I/O port number	Allocation	Area
0 ～ 15	Mini I/O input (RC8A, RC8)	Standard area

32 ～ 47	Not used.
48 ～ 55	Input by hand
56 ～ 63	Not used.
64 ～ 71	Output by hand
72 ～ 127	Not used.
