2.5 I/O Ports

In the M3A-HS86, all of the SH7086's I/O ports are connected to the extension bus connector. Some I/O ports are

connected to DIP switches and LEDs of the M3A-HS86 board. Users are free to use these ports.

Figure2.5.1 shows the Block Diagram of DIP Switch and LEDs in the M3A-HS86.

Table2.5.1 to Table 2.5.3 list a function of the SH7086 I/O ports in the M3A-HS86.
