31:24 ERROROFFSET Offset value in the Error to Voltage converter (two's RW 0x00
complement number).
23:16 ERRORGAIN Gain value in the Error to Voltage converter (two's RW 0x00
complement number).
15:8 INITVOLTAGE Set the initial voltage level of the SMPS. It must be RW 0x00
reconfigured before SmartReflex is enabled around a
new OPP.
7:4 RESERVED Write 0s for future compatibility. Read is undefined. R 0x0
3 TIMEOUTEN Enable or disable the timeout capability of the Voltage RW 0x0
Controller State Machine.
0x0: Timeout is disabled. Loop will wait indefinitely.
0x1: Timeout will occur when TIMEOUT cycles have
elapsed.
2 INITVDD Initializes the voltage in the Voltage Processor. RW 0x0
0x0: Reset the initialization bit.
0x1: The positive edge of InitVdd triggers a write of the
value in the InitVoltage into the Voltage Processor.
1 FORCEUPDATE Forces an update of the SMPS. RW 0x0
0x0: Reset the force bit.
0x1: The positive edge of ForceUpdate triggers an
update of the voltage to the SMPS.
0 VPENABLE Enables or disables the Voltage Processor. RW 0x0
0x0: Disables the Voltage Processor.
0x1: Enables the Voltage Processor.
