Bit 4
RST_EN_WD
0
This bit will enable the generation of a Reset pulse when a watchdog timer
time-out occurs.
0 = Disabled
1 = Enabled
Bit 3
RST_EN_FC
0
This bit will enable the generation of a Reset pulse after a frequency change
occurs.
0 = Disabled
1 = Enabled
Bit 2
WD_TO_STATUS
0
Watchdog Timer Time-out Status bit
0 = No time-out occurs (READ); Ignore (WRITE)
1 = time-out occurred (READ); Clear WD_TO_STATUS (WRITE)
Bit 1
WD_EN
0
0 = Stop and re-load Watchdog timer. Unlock W305B from recovery frequency
mode.
1 = Enable Watchdog timer. It will start counting down after a frequency change
occurs.
Note: W305B will generate system reset, re-load a recovery frequency, and
lock itself into a recovery frequency mode after a Watchdog timer time-out
occurs. Under recovery frequency mode, W305B will not respond to any attempt
to change output frequency via the SMBus control bytes. System software can
unlock W305B from its recovery frequency mode by clearing the WD_EN bit.
