5.2.9
I2C COMMAND PROTOCOL
The MCP47DA1 is a slave I2C device which supports
7-bit slave addressing. The slave address contains
seven fixed bits. Figure 5-9 shows the control byte
format.
5.2.9.1
Control Byte (Slave Address)
The Control Byte is always preceded by a START
condition. The Control Byte contains the slave address
consisting of seven fixed bits and the R/W bit. Figure 5-
the I2C address for the devices.

5.2.9.2
Hardware Address Pins
The MCP47DA1 does not support hardware address
bits.
5.2.10
GENERAL CALL
The General Call is a method that the Master device
can communicate with all other Slave devices.
The MCP47DA1 devices do not respond to General
Call address and commands, and therefore the
communications are Not Acknowledged.

A1
Note 1: The LSb of the 8-bit hex code is the I2C
Read/Write (R/W) bit. This hex value has
a R/W bit = “0” (write). If the R/W bit
reflected a read, this values would be
0x5D and 0x7D.
Note 1: The MCP47DA1 device supports two dif-
ferent I2C address (A0 and A1). This
allows two MCP47DA1 device on the
same I2C bus.
