Figure 2.16 GPIO header (GPIO1)
PCE-7214 provides 14-Pins pin header for Digital I/O usage. Refer to Appendix B for
detailed information on the pin assignments and programming guide in Appendix B.
2.17 CMOS clear (CMOS1)
The PCE-7214 single board computer contains a jumper that can erase CMOS data
and reset the system BIOS information. Normally this jumper should be set with pins
1-2 closed. If you want to reset the CMOS data, set CMOS1 to 2-3 closed for just a
few seconds, and then move the jumper back to 1-2 closed. This procedure will reset
the CMOS to its default setting.
