Read
≥1
START, Device Address, R/W = 0, Register Address to be read
RESTART, Device Address, R/W = 1, Data Read, STOP
If no STOP is issued, the Data Read can be continuously preformed. If the register
address falls within the range that allows address auto-increment, then register
address auto-increments internally after every byte of data being read. For register
address that falls within a non-incremental address range, the address will be kept
static throughout the entire read operations. Refer to the Memory Map table for the
address ranges that are auto and non-increment. An example of such a non-
increment address is FIFO.
Write
≥1
START, Device Address, R/W=0, Register Address to be written, Data Write, STOP
If no STOP is issued, the Data Write can be continuously performed. If the register
address falls within the range that allows address auto-increment, then register
address auto-increments internally after every byte of data being written in. For
register address that falls within a non-incremental address range, the address will
be kept static throughout the entire write operations. Refer to the Memory Map table
for the address ranges that are auto and non-increment. An example of a non-
increment address is Data Port for initializing the PWM commands.
