the SDATA low to acknowledge the receipt of the eight bits of data. The receiver may leave
the SDATA in high state if it does not acknowledge the receipt of the data.
4.2 Data input
The device samples the data input on SDATA on the rising edge of the SCLK. The SDATA
signal must be stable during the rising edge of SCLK and the SDATA signal must change
only when SCLK is driven low.
Table 8. Operating modes
Mode Byte 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.
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 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.
