Device Control Registers
DEV_CTRL1 (Offset = 00h)
DEV_CTRL1[3:0] shall not directly control the DEC or PSI functions, but rather they indicate which phases may be used.
However, if any of these bits are over-written then, DEC and/or PSI shall step up to the maximum allowable number of phases
and then resume normal operation.
