Description: NVM fail-safe shadow register 2 (see Section 5.4.5).

[7:4]

TSHDN_FLT_CNT_MAX[3:0]: setting of the maximum number of occurrences triggered by a thermal shutdown hard-

fault source.

0000: 0 hard-faults allowed (the PMIC goes in FAIL_SAFE_LOCK_STATE when the 1st hard-fault condition occurs)

0001: 1 hard-fault allowed (the PMIC goes in FAIL_SAFE_LOCK_STATE when the 2nd hard-fault condition occurs)

…

1110: 14 hard-faults allowed (the PMIC goes in FAIL_SAFE_LOCK_STATE when the 15th hard-fault condition occurs)

1111: ∞ hard-faults allowed (fail-safe disabled: the PMIC always restarts when a hard-fault condition occurs)

[3:0]

OCP_FLT_CNT_MAX[3:0]: setting of the maximum number of occurrences triggered by regulator overcurrent hard-fault

source.

0000: 0 hard-faults allowed (the PMIC goes in FAIL_SAFE_LOCK_STATE when the 1st hard-fault condition occurs)

0001: 1 hard-fault allowed (the PMIC goes in FAIL_SAFE_LOCK_STATE when the 2nd hard-fault condition occurs)

…

1110: 14 hard-faults allowed (the PMIC goes in FAIL_SAFE_LOCK_STATE when the 15th hard-fault condition occurs)

1111: ∞ hard-faults allowed (fail-safe disabled: the PMIC always restarts when a hard-fault condition occurs)
