ADDRESSING I2C DEVICES
(MCP23009)
The MCP23009 is a slave I2C device that supports 7-
bit slave addressing, with the read/write bit filling out
the control byte. The slave address contains four fixed
bits and three user-defined hardware address bits
(configured via ADDR pin). Figure 1-6 shows the
control byte format.
1.4.3
ADDRESSING SPI DEVICES
(MCP23S09)
The MCP23S09 is a slave SPI device. The slave
address contains seven fixed bits(no address bits) with
the read/write bit filling out the control byte. Figure 1-7
shows the control byte format.
