Power Supply ON Sequence

Notes: 1. Set VCMR to 1 when using internal electric volume.
            2. When NVM is in the status that the R61509V is shipped out, set the instruction register (R280h: VCM[6:0], and 
                UID[7:0]). If writing values to VCM[6:0] and UID[7:0] has been completed, setting this instruction register is 
                unnecessary.
