I2C module
STMPE801 is interface to the main processor using an I2C bus.
5.1
I2C address
Addressing scheme of STMPE801 is designed to allow up to 2 devices to be connected to
the same I2C bus.
Figure 3.
Addressing scheme
For the bus master to communicate to the slave device, the bus master must initiate a Start
condition anf followed by the slave device address. Accompanying the slave device address,
there is a Read/Write bit (R/W). The bit is set to 1 for Read and 0 for write operation.
If a match occurs on the slave device address, the corresponding device gives an
acknowledge on the SDA during the 9th bit time. If there is no match, it deselects itself from
the bus by not responding to the transaction.
