16.13.12 Register C7h PROCHOT Time Interval
Possible settings for PH_TI:
Note that changing this value while PROCHOT measurements are running may cause the monitoring circuit to produce a erroneous
value. To avoid alerts and invalid B_P_PROCHOT or H_P_PROCHOT Error Status values, only change this value while the chip
is programmed for S3 or S4/5.
