Device status register (addr 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.
