Field
As the VDD Regulator is shutdown once a LVRX condition is detected, The actual cause could be also a low voltage condition at the
VDDX regulator.
Watchdog Reset - Reset caused by an incorrect serving of the watchdog.
External Reset - Reset caused by the RESET_A pin driven low externally for > tRSTDF.
Wake-up Reset - Reset caused by a wake-up from Sleep mode. To determine the wake-up source, refer to
“Wake-up / Cyclic
Low Voltage Reset VDDX - Reset caused by a low voltage condition monitored at the VDDX output.
Low Voltage Reset VDD - Reset caused by a low voltage condition monitored at the VDD output.
Power On Reset - Supply Voltage was below V
