Write Volatile Memory
(C2:C0 = 010)
This Write command is used to update the volatile DAC
register value and Configuration bits. The EEPROM is
not affected by this command. Figure 6-2 shows an
example of this Write command.
The volatile DAC register and Configuration bits are
updated with the written date at the completion of the
ACK bit (falling edge of SCL).
After this ACK bit, the I2C master should generate a
Stop bit or the I2C master can repeat the 2nd
(3 command bits + 5 Configuration bits), and the 3rd
byte (8 data bits (b15:b08)), and the 4th byte (8 data
bits (b07:b00)). Repeating the 2nd through 4th bytes
allows a continuous command where the volatile DAC
register and Configuration bits can be updated without
the communication overhead of the device addressing
byte (1st byte).

Note 1: The device updates VOUT at the falling edge of the SCL at the end of this ACK pulse.
Note 1
2: The 2nd-4th bytes can be repeated after the 4th byte by continued clocking before issuing Stop bit.

3: ACK bit generated by MCP47X6.
