Slave device address
The slave device address is a 7 or 10-bit 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 STMPE2403
devices can be connected on a single I
Table 13. Slave device address
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 9
from the bus by not responding to the transaction.
