Description
General part information
PCA9539 Series
The system master can reset the PCA9539 in the event of a time-out or other improper operation by asserting a low in theRESETinput. The power-on reset puts the registers in their default state and initializes the I2C/SMBus state machine. AssertingRESETcauses the same reset/initialization to occur without de-powering the part.
The PCA9539 open-drain interrupt (INT) output is activated when any input state differs from its corresponding Input Port register state and is used to indicate to the system master that an input state has changed.
INTcan be connected to the interrupt input of a microcontroller. By sending an interrupt signal on this line, the remote I/O can inform the microcontroller if there is incoming data on its ports without having to communicate via the I2C bus. Thus, the PCA9539 can remain a simple slave device.
