Serial Interface
Registers
The settings of the AS2522 are stored in 16 registers. Each
register has 4 bit data width. Writing data into the AS2522 also
causes the sending of the AS2522 status information on Pin D0.
This information consists of the DC-current information (from the
Line Loss Compensation circuit) and the status of the power-on
reset circuit to test if AS2522 has already powered up.
