ADDRESSING I2C DEVICES
(MCP23018)
The MCP23018 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 1-6 shows the control byte
format.
1.4.3
ADDRESSING SPI DEVICES
(MCP23S18)
The MCP23S18 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.
