1.4.1
ADDRESSING I2C DEVICES
(MCP23008)
The MCP23008 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 (pins A2,
A1 and A0). Figure 1-2 shows the control byte format.
1.4.2
ADDRESSING SPI DEVICES
(MCP23S08)
The MCP23S08 is a slave SPI device. The slave
address contains five fixed bits and two user-defined
hardware address bits (pins A1 and A0), with the read/
write bit filling out the control byte. Figure 1-3 shows
the control byte format.
