Register description
6.16
60/71
Device status register (0x2D)
This read-only register provides fault and thermal-warning status information from the power
control block. Logic value 1 for faults or warning means normal state. Logic 0 means a fault
or warning detected on power bridge. The PLLUL=’1’ means that the PLL is not locked.

PLLUL

PLLUL: 0 = PLL locked, 1= PLL not locked.
FAULT: 0 = fault detected on power bridge, 1 = normal operation
UVFAULT: 0 = VCC1, VCC2 internally detected < under-voltage threshold.
OVFAULT: 0 = VCC1, VCC2 internally detected > over-voltage threshold.
OCFAULT: 0 = over-current fault detected
OCWARN: 0 = over-current warning.
TFAULT: 0 = thermal fault, junction temperature over-limit detection.
TWARN: 0 = thermal warning, junction temperature is close to the fault condition.
