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.

39h		 FIELD TYPE RESET DESCRIPTION
7-2 IDCHG_VTH 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.

Default: 16384 mA or 100000b

_PROFILE_ACOK		 R/W 0b

0b: disable <default at POR>

1b: enable

ChargeOption0[15] = 0 to assert PROCHOT pulse after adapter removal.

If PROCHOT_PROFILE_ACOK is enabled in PROCHOT after the adapter is removed, it will be pulled low.
