PRELIMINARY
Publication Release Date: Nov. 2000
- 121 - Revision 0.60
CRF5 (PLED mode register. Default 0x00)
Bit 7-6
: select PLED mode
= 00 Power LED pin is tri-stated.
= 01 Power LED pin is drived 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
: Enable the keyboard Reset output Low pluse when Time-out.
= 0 Disable
= 1 Enable
Bit 0
: Reserved
CRF6 (Default 0x00 if ENGMTO is 0, 0x0A if ENGMTO is 1)
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
note: The corresponding power on setting pin is pin 81 and its value is latched on the rising edge of
PWROK.
1: CRF6 is initialized to be 0x0A and CR30 of this logical device is initialized to be 0x01.
0: CRF6 is initialized to be 0x00 and CR30 of this logical device is initialized to be 0x00.
