11 PGB_STATUS Live register. 0x0 R
0 The voltage on the DRAIN pin is above the required threshold,
indicating that output power is considered good. This bit is the
logical inversion of the
PWRGD
pin on the part.
1 The voltage on the DRAIN pin is below the required threshold,
indicating that output power is considered bad.
