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 an address auto-

increment, then the 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 is kept static throughout

the entire read operations. Refer to the memory map table for the

address ranges that are auto and non-increment.

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 the register address auto-increments internally after

every byte of data being written in. For those register addresses that

fall within a non-incremental address range, the address is kept static

throughout the entire write operation. Refer to the memory map table

for the address ranges that are auto and non-increment.
