The addressing scheme of STMPE610 is designed to allow up to 2 devices to be connected
to the same I
Figure 4.
Table 6.
For the bus master to communicate to the slave device, the bus master must initiate a Start
condition and be followed by the slave device address. Accompanying the slave device
adress, 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 9
responding to the transaction.
