data to this slave and reads data from this slave.
When a master does not wish to relinquish the bus (which occurs by generating a STOP condi-
tion), a repeated START condition (Sr) must be generated. This condition is identical to the start
condition (SDA goes high-to-low while SCL is high), but occurs after a data transfer acknowledge
pulse (not the bus-free state). This allows a master to send “commands” to the slave and then
receive the requested information or to address a different slave device. This sequence is shown
in
