Summarizing this section: The POK block diagram shows a comparator with:
| Element of POK | Point of control |
|---|---|
| resistor divider | *POK*_CTRL registers |
| hysteresis enable | |
| comparator enable | *PRG*_CTRL |
| mux on the output | *POK*_CTRL registers |
The output of the POR / PRG_PP / POK voltage monitoring goes to the ESM. Each undervoltage / overvoltage condition has its own bit in the ESM, and the ESM can be programmed to respond to these bits as an interrupt and/or to generate an external signal to the system.
