Preliminary
1996 Microchip Technology Inc.
When a master does not wish to relinquish the bus (by
generating a STOP condition), a repeated START (Sr)
must be generated. This condition is identical to the
START (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 Figure 7-10.

For 7-bit address:
S Slave Address R/W A DATA A DATA A/A
P
"0" (write)
data transferred
(n bytes - acknowledge)
A master transmitter addresses a slave receiver with a
7-bit address. The transfer direction is not changed.
For 10-bit address:
S Slave Address
first 7 bits
R/W A1 Slave Address
second byte
A2
(write)
A master transmitter addresses a slave receiver with a
10-bit address.
From master to slave
From slave to master
A = acknowledge (SDA low)
A = not acknowledge (SDA high)
