Register 15 is used to mask or unmask various warnings for use by the interrupt (nINT) pin. When any bit in this register is masked, the

associated event does not trigger the nINT pin.

5 MASK_TEMP R/W 0 = temperature overheat warning does not trigger the interrupt pin (default).

1 = temperature overheat warning triggers the interrupt pin.

4 MASK_LVIN R/W 0 = low voltage input warning does not trigger the interrupt pin (default).

1 = low voltage input warning triggers the interrupt pin.

3 MASK_PWRG4 R/W 0 = power-good warning on Channel 4 does not trigger the interrupt pin (default).

1 = power-good warning on Channel 4 triggers the interrupt pin.

2 MASK_PWRG3 R/W 0 = power-good warning on Channel 3 does not trigger the interrupt pin (default).

1 = power-good warning on Channel 3 triggers the interrupt pin.

0 = power-good warning on Channel 2 does not trigger the interrupt pin (default).

1 = power-good warning on Channel 2 triggers the interrupt pin.

0 MASK_PWRG1 R/W 0 = power-good warning on Channel 1 does not trigger the interrupt pin (default).

1 = power-good warning on Channel 1 triggers the interrupt pin.

The write-only Register 17 is used to reset all registers to their default values.
