W83627HF/F
PRELIMINARY
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
CRF7 (Default 0x00)
Bit 7: Mouse interrupt reset Enable or Disable
= 1 Watch Dog Timer is reset upon a Mouse interrupt
= 0 Watch Dog Timer is not affected by Mouse interrupt
Bit 6: Keyboard interrupt reset Enable or Disable
= 1 Watch Dog Timer is reset upon a Keyboard interrupt
= 0 Watch Dog Timer is not affected by Keyboard interrupt
Bit 5: Force Watch Dog Timer Time-out, Write only*
= 1 Force Watch Dog Timer time-out event; this bit is self-clearing.
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.
13.10 Logical Device 9 (GPIO Port 3 This power of the Port is standby source (VSB) )
CR30 (Default 0x00)
Bit 7 - 1: Reserved.
Bit 0: = 1 Activate GPIO3.
= 0 GPIO3 is inactive.
CRF0 (GP30-GP35 I/O selection register. Default 0xFF Bit 7-6: Reserve)
When set to a '1', respective GPIO port is programmed as an input port.
When set to a '0', respective GPIO port is programmed as an output port.
CRF1 (GP30-GP35 data register. Default 0x00 Bit 7-6: Reserve)
If a port is programmed to be an output port, then its respective bit can be read/written.
If a port is programmed to be an input port, then its respective bit can only be read.
CRF2 (GP30-GP35 inversion register. Default 0x00 Bit 7-6: Reserve)
When set to a '1', the incoming/outgoing port value is inverted.
When set to a '0', the incoming/outgoing port value is the same as in data register.
