MS4525DO
1.5 Data transfer format
an acknowledge bit. Data is transferred with the most significant bit (MSB) first.
A data transfer sequence is initiated by the master generating the Start condition (S) and sending a header byte.
The I2C header consists of the 7-bit I2C device address and the data direction bit (R/_W).
The value of the R/_W bit in the header determines the data direction for the rest of the data transfer sequence.
If R/_W = 0 (WRITE) the direction remains master-to-slave, while if R/_W = 1 (READ) the direction changes to
slave-to-master after the header byte.
1.6 Command Set and data Transfer Sequences
slave sends an acknowledge (ACK) indicating success. The sensor has four I2C read commands: Read_MR,
Read_DF2, Read_DF3, and Read_DF4.Figure 1.6 shows the structure of the measurement packet for three of
the four I2C read commands, which are explained in sections 1.6.1 and 1.6.2
MS4525DO
Data is transferred in byte packets in the I2C protocol, which means in 8-bit frames. Each byte is followed by
The I2C master command starts with the 7bit slave address with the 8th bit =1 (READ).The sensor as the
