FUNCTIONAL DEVICE OPERATION
LOGIC COMMANDS AND REGISTERS
I²C REGISTER DISTRIBUTION
Each regulator has a fault register that records any fault
that occurs in that regulator. Then there is a regulator fault
reporting register that the processor can access at all times
to see if any fault had occurred.
There are also the IC general use registers. Those
registers are also split between status reporting registers and
processor programmable registers.
This distribution keeps each regulator’s registers bundled
together which makes it easier for the user to access one
regulator at a time.
