STV6411A
I
Data transfers follow the usual I2C format: after the start condition (S), a 7-bit slave address is sent, followed
by an eighth bit which is a data direction bit (W). A 8-bit subadress is sent to select a register, followed by
a 8-bit data word to put in it.
The IC’s I2C bus decoder permits the automatic incrementation mode in write mode.
String Format
Write only mode (S : start condition, P : stop condition, A : acknowledge)
Read only mode
Slave Address
Auto Increment Mode
I
Write Address : 1001 01X0
Read Address : 1001 01X1
Address Selection Pin Grounded : X = 0, write address = 94HEX, read address = 95HEX
Address Selection Pin to Supply : X = 1, write address = 96HEX, read address = 97HEX
