W83637HF
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.
8.3.9 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.
CRF3 (SUSLED mode register. Default 0x00)
Bit 7-6 : select Suspend LED mode
= 00 Suspend LED pin is drove low.
= 01 Suspend LED pin is tri-stated.
= 10 Suspend LED pin is a 1Hz toggle pulse with 50 duty cycle.
= 11 Suspend LED pin is a 1/4Hz toggle pulse with 50 duty cycle.
This mode selection bit 7-6 keep its settings until battery power loss.
Bit 5 - 0 : Reserved.
