2. This product can multiplex the IICA input/output pin function to multiple ports. When a port is configured for
multiplexing on the IICA pin, the
N-channel open-drain output (VDD/EVDD
withstand
voltage) mode
of the port is
designed to automatically open, i.e. the POMxx register does not require user settings.
