7.12.2 START and STOP conditions
7.12.3 Bit transfer
7.12.4 Acknowledge
Both data and clock lines remain HIGH when the bus is not busy. A HIGH-to-LOW
transition of the data line, while the clock is HIGH is defined as the START condition
(S). A LOW-to-HIGH transition of the data line while the clock is HIGH is defined as a
STOP condition (P); see
One data bit is transferred during each clock pulse. The data on the SDA line must
remain stable during the HIGH period of the clock pulse as changes in the data line at
this time will be interpreted as a control signal; see
The number of data bytes transferred between the START and the STOP conditions
from the transmitter to the receiver is unlimited. Each byte of eight bits is followed by
an acknowledge bit. The acknowledge bit is a HIGH level signal put on the bus by the
transmitter during which time the master generates an extra acknowledge-related
clock pulse.
A slave receiver which is addressed must generate an acknowledge after the
reception of each byte. Also a master receiver must generate an acknowledge after
the reception of each byte that has been clocked out of the slave transmitter.
