Revision 1.3
CRF3 (Default 0x00)
Bit 7 - 4 : These bits select IRQ resource for IRQIN1.
Bit 3 - 0 : These bits select IRQ resource for IRQIN0.
CRF4 (Reserved)
CRF5 (PLED mode register. Default 0x00)
Bit 7-6
: select PLED mode
= 00 Power LED pin is tri-stated.
= 01 Power LED pin is driven low.
= 10 Power LED pin is a 1Hz toggle pulse with 50 duty cycle
= 11 Power LED pin is a 1/4Hz toggle pulse with 50 duty cycle.
Bit 5-4
: Reserved
Bit 3
: select WDTO count mode.
= 0 Second
= 1 Minute
Bit 2
: Enable the rising edge of keyboard Reset(P20) to force Time-out event.
= 0 Disable
= 1 Enable
Bit 1-0
: Reserved
CRF6 (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. If the Bit 7 and Bit 6 are set, any Mouse
Interrupt or Keyboard Interrupt event will also cause the reload of previously-loaded non-zero 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
