I2C Interface

6.4
Data input
The device samples the data input on SDATA on the rising edge of the SCLK. The SDATA
signal must be stable during the rising edge of SCLK and the SDATA signal must change
only when SCLK is driven low.
6.5
Slave device address
The slave device address is a 7 address, where the least significant 2-bit are programmable.
These 2-bit values will be loaded in once upon reset and after that these 2 pins no longer be
needed with the exception during General Call. Up to 4 STMPE2401 devices can be
connected on a single I2C bus.
6.6
Memory addressing
For the bus master to communicate to the slave device, the bus master must initiate a Start
condition and 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
acknowledgement 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.
