4.10.3 Keyboard and PS/2 mouse connector

The CPC-2245N provides a keyboard and PS2 mouse interface
through a 40-pin FPC connector (CN4) for connection of PS/2
keyboard and PS/2 mouse.

In most cases, especially in embedded applications, a keyboard is
not used. The standard PC/AT BIOS will report an error or fail
during power-on self-test (POST) after a reset if the keyboard is not
present. The CPC-2245N's BIOS "Standard CMOS Features" allows
you to select "Halt on" under the "All, but keyboard" or "All, but
disk/key" selection. This allows no-keyboard operation in embed-
ded system applications without the system halting under POST
(power on self test).
