S = START condition - SDA goes from high to low while SCL is high
A = Acknowledge - the device being written to, pulls down on data line (SDA) during the acknowledge
clock pulse.
P = STOP condition - SDA goes from low to high while SCL is high.

Default mode is 0000 0000 which corresponds to all outputs being off, low power mode.
Bit 5 Controls the output voltage of REG4. A ’0’ corresponds to 8V and a ’1’ corresponds to 10V.
(*) ESR of output capacitors should be between 0.1
and 5.0
