Bit 7 – FLTMSK Fault Masking bit

If the bit is 1, it will prevent nINTO from being asserted LOW upon FLT = 1.

Bit 6 – HCPEN Short-Circuit Protection Hiccup Mode Enable

If HCPEN = 1, a short-circuit event will cause hiccup-mode response with unlimited Soft-Start retries, without shutting down the other channels. If HCPEN = 0, a short circuit event on the channel will cause immediate shutdown of ALL channels, and a new Start-Up Sequence will automatically be attempted after a 100 ms delay.

Bit 5 – DISCH Active Output Discharge Control

DISCH = 1 enables Active Output Discharge when a channel is turned OFF, DISCH = 0 disables it.

Bit 4 – PHASE Regulator Phase Control

Setting the bit to 1 will cause the regulator to operate 180° out of phase with the oscillator, and clearing the bit to 0 will cause the regulator to operate in phase with the oscillator.
