Communication specification
Communication specifications are indicated as below:
Serial Interface (I
Terms used in I
[Start] and [Stop] conditions
Data transmission
Sending and receiving data through I
line (SCL). This bus enables 8-bit bi-directional serial data to transmit at the maximum speed of 400kbits (fast mode).
This is not compatible with Hs mode.
The following terms are used in I
[Start] condition is required at the start of data communication and [Stop] condition at the end of data communication.
The condition in which the SDA line changes from [H] to [L] with SCL at [H] is called the [Start] condition. The
condition in which the SDA line changes from [L] to [H] with SCL at [H] is called the [Start] condition.
The length of each byte which is output to SDA line is always 8 bits. An acknowledge bit is needed after each byte.
Data is transmitted sequentially from the most significant bit (MSB).
During the data transfer, the slave address is transmitted after the [Start] condition (S).
Data transfer is always ended by the [Stop] condition (P) generated by the master.
