CRF4 (Default 0x00)
Watch Dog Timer Time-out value. Writing a non-zero value to this register causes the counter to
load the value to Watch Dog Counter and start counting down. Reading this register returns current
value in Watch Dog Counter instead of Watch Dog Timer Time-out value.
Bit 7 - 0
= 0x00 Time-out Disable
= 0x01 Time-out occurs after 1 second/minute
= 0x02 Time-out occurs after 2 second/minutes
= 0x03 Time-out occurs after 3 second/minutes
................................................
= 0xFF Time-out occurs after 255 second/minutes
CRF5 (Default 0x00)
Bit 7 ~ 6
: Reserved .
Bit 5
: Force Watch Dog Timer Time-out, Write only*
= 1

Bit 4
: Watch Dog Timer Status, R/W
= 1
Watch Dog Timer time-out occurred.
= 0
Watch Dog Timer counting
Bit 3 -0
: These bits select IRQ resource for Watch Dog. Setting of 2 selects SMI.
10.12 Logical Device 9 (GPIO Port 2 ~ GPIO Port 4 )
CR30 (Default 0x00)
Bit 7 ~ 3
: Reserved.
Bit 2
= 1
Activate GPIO4.
= 0
GPIO4 is inactive
Bit 1
= 1
Activate GPIO3.
= 0
GPIO3 is inactive
Bit 0
= 1
Activate GPIO2.
= 0
GPIO2 is inactive.
CR60,61(Default 0x00,0x00).
These two registers select the GP2,3,4 base address(0x100:FFE) ON 3 bytes boundary.
IO address: : CRF1 base address
IO address + 1 : CRF3 base address
IO address + 2 : CRF7 base address
