This command writes to the DAC input registers and EEPROM sequentially from a start
channel to the channel D. The input register is written at the ACK pulse of the input data
byte of each register. However, the EEPROM are written altogether at the same time
sequentially at the end of the last byte. The EEPROM writing activity can be monitored
through the RDY/BSY bit and pin. See the MCP4728 data sheet for details.
