2.3.2
Start and Stop Conditions
Both SCL and SDA remain high when the interface is not busy. A master signals the beginning of a transmission with a START (S)
condition by transitioning SDA from high to low while SCL is high. When the master has finished communicating with the slave,
it issues a STOP (P) condition by transitioning SDA from low to high while SCL is high. The bus is then free for another
transmission.
Figure 6. Start and Stop Conditions
2.3.3
Bit Transfer
One data bit is transferred during each clock pulse (Figure 7). The data on SDA must remain stable while SCL is high.
Figure 7. Bit Transfer
2.3.4
Acknowledge
The acknowledge bit is a clocked 9th bit (Figure 8) which the recipient uses to handshake receipt of each byte of data. Thus each
byte transferred effectively requires 9 bits. The master generates the 9th clock pulse, and the recipient pulls down SDA during
the acknowledge clock pulse, such that the SDA line is stable low during the high period of the clock pulse. When the master is
transmitting to the MPR083, the MPR083 generates the acknowledge bit because the MPR083 is the recipient. When the
MPR083 is transmitting to the master, the master generates the acknowledge bit because the master is the recipient.
