When the REG0x38[7:0] are set to be disabled, the PROCHOT event associated with that bit will not be reported
in the PROCHOT status register REG0x22[7:0] any more, and the PROCHOT pin will not be pulled low any
more if the event happens.

R/W
100000b IDCHG Threshold
6 bit, range, range 0 A to 32256 mA, step 512 mA. There is a 128 mA offset.
Measure current between SRN and SRP.
Trigger when the discharge current is above the threshold.
If the value is programmed to 000000b, PROCHOT is always triggered.
