Current and Voltage Monitor and 4 LED Drivers
START and STOP Conditions
Both SCL and SDA idle high when the bus is not busy.
A master device signals the beginning of a transmission
with a START condition (see Figure 3) by transitioning
SDA from high to low while SCL is high. The master
device issues a STOP condition (see Figure 6) by transi-
tioning SDA from low to high while SCL is high. A STOP
condition frees the bus for another transmission. The bus
remains active if a REPEATED START condition is gener-
ated, such as in the block read protocol (see Figure 7).
