Description
Bypass Ballast Low Voltage. This field monitors the NOT of nBYPASS_BALLAST_LV[3:0] bus.
0 BB_LV[n] = NOT (nBYPASS_BALLAST_LV[n] = ‘1’); where n goes from 3 down to 0
1 BB_LV[n] = NOT (nBYPASS_BALLAST_LV[n] = ‘0’); where n goes from 3 down to 0

39.7.5 PMUCTRL interrupt request status register (PMUCTRL_IRQS)
This register allows you to read and clear the various PMU interrupt status bits. To clear these bits, write
a ‘1’ to them.
