Description
This bit specifies when the flag is set.
0 = after debounce.
1 = immediately.
These bits specify the action that the part takes in response to the flag.

Description
Setting this bit to 1 means that the VDD OV and VCORE OV flags are ignored.
This bit specifies whether the part downloads the EEPROM contents before it restarts.
1 = if the part shuts down, it downloads the EEPROM contents again before restarting.
0 = if the part shuts down, it does not download the EEPROM contents again before restarting.
Setting this bit to 1 means that there is a 500 μs debounce before the part shuts down. Setting
this bit to 0 means that there is a 2 μs debounce before the part shuts down.
When an accurate OCP flag is set, there is a debounce time before the flag action is performed.
These bits set the flag debounce time. The ADC sampling rate adds a variable latency from
2.62 ms to 5.24 ms to this debounce time.
