MCP23S08-E/P is an 8-bit I/O Expander with a serial interface that provides 8-bit, general-purpose, parallel I/O expansion for SPI applications. 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. The system master can read all registers. The interrupt capture register captures port values at the time of the interrupt, thereby saving the condition that caused the interrupt
