APPLICATION INFORMATION
I2C Operation (continued)
The read cycle protocol begins with a START bit, followed by two 8-bit words, another START bit, another two
8-bit words and ends with a STOP bit. The first two 8-bit words are similar to the write cycle, with a low LSB for
the device address, and instruct the device which internal register will be polled. A START bit after the second
word interrupts the write cycle after the internal register is defined. The next 8-bit word following the second
START bit is once again the device address, however, the LSB (A0) is now high indicating the device is expected
to return the data from the selected internal register. After the ACKNOWLEDGE bit, the TPS2341 drives the
SDA line and return the 8-bits of data from the internal register.
