TSD
Thermal shutdown
1
Status Register 2
‘0’
TW
Thermal warning
1
Status Register 0
‘0’
WD
Watchdog event
1
Status Register 0 ‘1’ = watchdog reset after time−out
‘0’
NOTE: WD − This bit indicates that the watchdog timer has not been cleared properly. If the master reads that WD is set to “1” after reset,
it means that a watchdog reset occurred (warm boot) instead of POR (cold boot). WD bit will be cleared only when the master
writes “0” to WDEN bit.
