2.5 I/O Ports

All of the SH7137 I/O ports are connected to the expansion bus connectors on the M3A-HS37.
Some I/O ports are connected to the DIP switches and LEDs, which are allowed for user.
Figure 2.5.1 shows the DIP switches and LEDs connection diagram.
Table 2.5.1 lists the I/O port features.
Note: Unused ports are open to allow for expansion on the M3A-HS37.
(PA6 to PA9, PB0, PB1, PB5, PD8-PD10, PE0, PE3, and PE8)
Set these unused ports as output at first when using the M3A-HS37.
When some ports of the SH7137 MCU are unused on the user system, the pull-up or pull-down process is recommended.
