*1: Data write to this address (1000) is allowed for the
most significant two bits only. The least significant 6 bits are
only used for the factory test. When writing data, always write
0 to these six bits.

*1: When switching the output voltage of VO1_SENSE (2),
write 1 to the PGOOD1 (2) Mask bit in advance to fix the rest
output to High for preventing erroneous operation.
1 = DDC2 on
0 = DDC2 off
SREG1: Series Pass Regulator Channel1 output Control
1 = Regulator on
0 = Regulator off
*2: When turning DDC2 OFF, set the PGOOD2 bit to High
to Mask PGOOD2. If you turn DDC2 OFF, the power switch
2 also turns OFF.
