Port Inputs
I/O port inputs switch at the CMOS-logic levels as
determined by the expander鈥檚 supply voltage, and are
overvoltage tolerant to +6V, independent of the
expander鈥檚 supply voltage.
I/O Port Input Transition Detection
All I/O ports configured as inputs are monitored for
changes since the expander was last accessed through
the serial interface. The state of the ports is stored in an
internal 鈥渟napshot鈥� register for transition monitoring. The
snapshot is continuously compared with the actual input
conditions, and if a change is detected for any port input,
INT is asserted to signal a state change. The input ports
are sampled (internally latched into the snapshot register)
and the old transition flags cleared during the I2C acknowl-
edge of every MAX7325 read and write access. The previ-
ous port transition flags are read through the serial
interface as the second byte of a 2-byte read sequence.
