General Description
The MAX7319 2-wire serial-interfaced peripheral fea-tures eight input ports with selectable internal pullups, overvoltage protection to +6V, and transition detection with interrupt output.
All input ports are continuously monitored for state changes (transition detection). Transitions are latched, allowing detection of transient changes. Any combination of inputs can be selected using the interrupt mask to assert the INT output. When the MAX7319 is subsequently accessed through the serial interface, any pending interrupt is cleared.
