Technical Note
● I 2 C BUS format
The writing operation is based on the I 2 C slave standard.
? Slave address
A7 A6 A5 A4 A3 A2 A1 R/W
ADDSEL=L 0 0 1 1 0 1 0 0
ADDSEL=H 0 0 1 1 0 1 1 0
Slave address can be changed with the external terminal ADDSEL.
? Bit Transfer
SCL transfers 1-bit data during H. SCL cannot change signal of SDA during H at the time of bit transfer. If SDA changes
while SCL is H, START conditions or STOP conditions will occur and it will be interpreted as a control signal.
SDA
SCL
SDA a state of stability :
Data are effective
SDA
It can change
? START and STOP condition
When SDA and SCL are H, data is not transferred on the I 2 C- bus. This condition indicates, if SDA changes from H to L
while SCL has been H, it will become START (S) conditions, and an access start, if SDA changes from L to H while SCL
has been H, it will become STOP (P) conditions and an access end.

? Acknowledge
It transfers data 8 bits each after the occurrence of START condition. A transmitter opens SDA after transfer 8bits data, and
a receiver returns the acknowledge signal by setting SDA to L.
