Register 3: Power-Temp Brown Out Control (PTBOCTL), offset 0x038
This register determines, based on an individual event level, the appropriate next level of action (for
example, NONE, System Control Interrupt, NMI, or reset) when an event occurs.
Power-temperature event actions are directed to the core as a System Control Interrupt or NMI.
When a reset occurs, its behavior is controlled by the Reset Behavior Control (RESBEHAVCTL)
register. If one of the events configured in the PTBOCTL register causes a reset, it is registered as
a BOR interrupt in the Reset Cause (RESC) register.
Note: V
DDA
is the supply voltage to the analog components of the device and V
DD
is the supply
voltage to the digital components of the device.
