PCA9500
8-bit I2C-bus and SMBus I/O port with 2-kbit EEPROM
7.3 I/O operations
(Refer also to Figure 5.)
Each of the PCA9500's eight I/Os can be independently used as an input or output.
Output data is transmitted to the port by the I/O Write mode (see Figure 7). Input I/O data
is transferred from the port to the microcontroller by the Read mode (see Figure 8).
