Programming sequence

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 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 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. For those register addresses that fall within

a non-incremental address range, the address will be kept static

throughout the all 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.
