DESCRIPTION
The device consists of a 16-bit quasi-bidirectional port and
an I
consumption and includes latched outputs with high
current drive capability for directly driving LEDs. It also
possesses an interrupt line (INT) which can be connected
to the interrupt logic of the 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 I
the PCF8575 is an I
Every data transmission from the PCF8575 must consist
of an even number of bytes, the first byte will be referred
to as P07 to P00 and the second byte as P17 to P10.
The third will be referred to as P07 to P00 and so on.
