Revision 1.0
Bit 4: Real Time Clock Function Enable
1: Enable RTC Block
0: Power down RTC Block
Bit 3: Keyboard Scan Function Enable
1: Enable {GP0, GP1, GP20~23} Keyboard Scan Function and GP3 Key Wakeup Interrupt Function.
0: Disable
Note:
To enable Keyboard Scan Function will switch {GP0, GP1, GP20~23} drive current from 12mA to 250uA.
Bit 2: Watch Dog Timer Function Enable
1: Enable WDT Block
0: Power down WDT Block
Bit 1: Whole Chip Power down Enable
1: Power down mode:
When there is no any external interrupt, Key Wake-up interrupt and LPC interrupt occurs or PS2
data line is low , W83L951DG/FG will stop external clock to enter power down mode, otherwise it will
clear this bit as 0 automatically.
0: Normal Mode:
When any external interrupt or Key Wake-up interrupt occurs or PS2 data line goes low, this bit will
clear this bit as 0 automatically.
Note: If whole chip power down mode and idle mode are both enabled, after leaving power down
mode, W83L951DG/FG will enter idle mode to wait for internal interrupt.
Bit 0: Whole Chip Idle Enable
1: Idle Mode:
When there is no any interrupt occurs, W83L951DG/FG will enter idle mode, otherwise it will clear this
bit as 0 automatically.
0: Normal Mode:
It will clear this bit as 0 when all interrupt events occur.
6.1.1.16
Chip Control 3 Register (CHIPCTRL3) (Default Value: 0000_0000)
Bit 7: FAN 2 Function Enable
1: Enable FAN1 Block (GP40 GPIO Function Disable)
0: Power down FAN1 Block
Bit 6: FAN 1 Function Enable
1: Enable FAN2 Block (GP41 GPIO Function Disable)
0: Power down FAN2 Block
