restart
R/W
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.

debounce
Accurate OCP debounce
for CS1 and CS2
R/W
R/W
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.
