LED High-Current Regulator Headroom Voltage Monitoring bit.
This bit returns the headroom voltage status of the LED high-current regulators.
This value is being updated at the end of a flash strobe, before the LED current
ramp-down phase.
0: Low headroom voltage.
1: Sufficient headroom voltage.

Output Voltage Selection bits.
In read mode, these bits return the result of the high-current LED forward voltage
self-calibration procedure.
In write mode, these bits are used to set the target output voltage (see Down-
Mode in Voltage Regulation Mode). In applications requiring dynamic voltage
control, care must be take to set the new target code after voltage mode
operation has been enabled (MODE_CTRL[1:0] = 11 or ENVM bit = 1).
