Multiple-register read.
9.4.4.1
Current address read
The transfer format description for a current address read is given in
Table 43
. For
illustration, see
Figure 10
.
9.4.4.2
Random address read—Single read
Table 44
describes the transfer format for a single-byte read.
Figure 11
illustrates the byte
sequence.
9.4.4.3
Random address read—Multiple read
The transfer format description for a multiple-byte read is given in
Table 45
.
Figure 11
illustrates the byte sequence.

Transfer format description for current address read
Description
master starts with a START condition
master transmits device address and read command bit R/W = 1
slave generates an acknowledgment
slave transmits and master reads data from register K. If the start address is
not specified, the read operation starts from where the index register is
pointing to because of a previous read or write operation.
master terminates the read operation by generating a No Acknowledge
master generates a stop condition
No ACK
