Figure 11-19 and Figure 11-20 show Master-transmit-
ter and Master-receiver data transfer sequences.
When a master does not wish to relinquish the bus (by
generating a STOP condition), a repeated START con-
dition (Sr) must be generated. This condition is identi-
cal to the start condition (SDA goes high-to-low while
SCL is high), but occurs after a data transfer acknowl-
edge pulse (not the bus-free state). This allows a mas-
ter to send “commands” to the slave and then receive
the requested information or to address a different
slave device. This sequence is shown in Figure 11-21.
