TURN OFF EVENTS
Power Button Press
an interrupt (PWRONxI), but will not directly power off the part. The product is powered off by the processor's response to this
interrupt, which will be to pull WDI low. Pressing the power button is therefore under normal circumstances not considered as a
turn off event for the state machine.
(Memory Hold or User Off) for a quicker restart than the default transition into the Off state.
Power Button System Reset
By default, the system reset function is disabled but can be enabled by setting the PWRONxRSTEN bits. When enabled, a 4
second long press on the power button will cause the device to go to the Off mode and as a result the entire application will power
down. An SYSRSTI interrupt is generated upon the next power up. Alternatively, the system can be configured to restart
automatically by setting the RESTARTEN bit.
Thermal Protection
while the thermal protection is still being tripped. The part will remain in Off mode until cooling sufficiently to accept a Turn On
event. There are no specific interrupts related to this other than the warning interrupts.
Under-Voltage Detection
mode if PCUT is not enabled, or if the PCT timer expires when PCUT is enabled.
TIMERS
A synchronization error of up to one clock period may occur with respect to the occurrence of an asynchronous event. The
duration listed below is therefore the effective minimum time period.

System restart may occur after a system reset. This is an optional function, see also the following Turn Off events section. BP
User shut down of a product is typically done by pressing the power button connected to the PWRONx pin. This will generate

A secondary application of the PWRON pin is the option to generate a system reset. This is recognized as a Turn Off event.
If the die gets overheated, the thermal protection will power off the part to avoid damage. A Turn On event will not be accepted
When the voltage at BP drops below the under-voltage detection threshold UVDET, the state machine will transition to Off
