Programming sequence
Start, Device address, R/W = 0, Register address to be read
Restart, Device address, R/W = 1, Data Read, Stop
≥1
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.
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-
≥1
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 will be kept
static throughout the entire write operation. Refer to the memory map
table for the address ranges that are auto and non-increment.
