Remote 16-bit I/O expander for I2C-bus with interrupt
8.3 Reading from a port (Input mode)
All ports programmed as input should be set to logic 1. To read, the master
(microcontroller) rst addresses the slave device after it receives the interrupt. By setting
the last bit of the byte containing the slave address to logic 1 the Read mode is entered.
The data bytes that follow on the SDA are the values on the ports.
If the data on the input port changes faster than the master can read, this data may be
lost.
