The continuous (or invalid) mode of operation is selected by setting the PGOOD_MODE bit to 1 in the PGOOD_CTRL_2 register.
For the continuous mode of operation, PGOOD behaves as follows:
The PG_FAULT register bits are latched, and maintain the fault information until the host clears the fault bit by writing 1 to the bit. The PGOOD signal also indicates a thermal shutdown and input overvoltage interrupts, which are cleared by clearing the interrupt bits.
When the regulator voltage is transitioning from one target voltage to another, the PGOOD signal becomes inactive.
