State
CPFail Charge Pump Failure 1 Status Register 0
‘0’ = no failure
‘1’ = failure: indicates that the charge pump does not
reach the required voltage level.
‘0’
WD Watchdog event 1 Status Register 0
This bit indicates the watchdog timer has not been
cleared properly in time. If the master reads that WD
is set to “1” after reset, it means that a watchdog re-
set occurred (warm boot) instead of power−on−reset
(cold boot). WD bit will be cleared only when the
master writes “0” to WDEN bit.
