CMOS clear (CMOS1)

The PCA-6012 single board computer contains a jumper that can erase CMOS data
and reset the system BIOS information. Normally this jumper should be set with
pins1-2 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.

Watchdog timer output (JWDT1)

The PCA-6012 contains a watchdog timer that will reset the CPU in the event the
CPU stops processing. This feature means the PCA-6012 will recover from a soft-
ware failure or an EMI problem. The JWDT1 jumper settings control the outcome of
what the computer will do in the event the watchdog timer is tripped.

System Memory

The PCA-6012 has two sockets for 204-pin DDR3 800MHz SO-DIMM memory mod-
ules. All these sockets use 1.5 V unbuffered double data rate synchronous DRAMs.
They are available in capacities of 512 MB, 1 GB, and 2 GB. The sockets can be
filled in any combination with DIMMs of any size, giving a total memory size up to 2
GB (for VG N455 SKU) and up to 4 GB (for G2 D525 SKU).
