... I/Os are needed for ACPI, power switches, sensors, push buttons, LEDs and so on. The MCP23016 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 1 ...

... MCP23016 1.7.1 DATA PORT REGISTERS Two registers provide access to the two GPIO ports: • GP0 (provides access to data port GP0) • GP1 (provides access to data port GP1) A read from this register provides status on pins of these ports. A write to these registers will modify the output latch registers (OLAT0, OLAT1) and data output ...

... I C bus and GPIO. 1.9 Interrupt Logic The MCP23016 asserts the open-drain interrupt output (INT) low when one of the port pins changes state. Only those pins that are configured as an input can cause an interrupt. Pins defined as an output have no effect on INT ...

... WRITING THE REGISTERS To write to a MCP23016 register, the Master I needs to follow the requirements, as illustrated in Figure 1-3. First, the device is selected by sending the slave address and setting the R/W bit to logic ‘0’. The command byte is sent after the address and determines which register will be written. Table 1-3 shows the relationship of the command byte and register ...

First, the device is selected by sending the slave address and setting the R/W bit to logic ‘0’. The command byte is sent after the address and determines which register will be read. A restart condition is generated and the device address is sent again with the R/W bit set to logic ‘ ...
