I2C BUS SPECIFICATIONS
5 I2C BUS SPECIFICATIONS
40/76
Data transfers follow the usual I2C format: after the
start condition (S), a 7-bit slave address is sent,
followed by an eight-bit which is a data direction bit
(W). An 8-bit sub-address is sent to select a regis-
ter, followed by an 8-bit data word to be included in
the register.
String Format
Write only mode (S = start condition, P = stop condition, A = acknowledge)
S
SLAVE ADDRESS
The IC’s I2C bus decoder permits the automatic in-
crementation mode in write mode.
The circuit operates up to clock frequencies of
400 kHz.
