TABLE B-2:
All devices (slave addresses) respond to the I
device supports a fixed number of word addresses (see section B.6 Slave Devices
below). The word address is automatically incremented during a transaction for
sequential access of the device registers. If the word address is incremented beyond
the end of the supported address range, the address will “wrap”.

Figure B-1 shows the Master and Slave legend used for Figures B-2 through B-4.
FIGURE B-1:
Write Byte(s) – This transaction is used to write one or more bytes. The maximum
number of bytes is slave-dependant.
