Description
The MCP23X08 device provides 8-bit, general purpose, parallel I/O expansion
for I2C bus or SPI applications. The two devices differ in the number of
hardware address pins and the serial interface:
• MCP23008 – I2C interface; three address pins
• MCP23S08 – SPI interface; two address pins
The MCP23X08 consists of multiple 8-bit Configuration registers for input, output and polarity selection. The system master can enable the I/Os as either inputs or outputs by writing the I/O Configuration bits. The data for each input or output is kept in the corresponding Input or Output register. The polarity of the Input Port register can be inverted with the Polarity Inversion register. All registers can be read by the system master.
The interrupt output can be configured to activate under two conditions
(mutually exclusive):
1. When any input state differs from its corresponding Input Port register
state, this is used to indicate to the system master that an input state has
changed.
2. When an input state differs from a preconfigured register value (DEFVAL
register).
The Interrupt Capture register captures port values at the time of the interrupt, thereby saving the condition that caused the interrupt.
The Power-on Reset (POR) sets the registers to their default values and initializes the device state machine. The hardware address pins are used to determine the device address.
