Gain And Attenuation Volume Controller IC

BUS INTERFACE

Data are transmitted to and from the MCU to the MS6260 via the SDA and SCL. The SDA and SCL make up the

BUS interface. It should be noted that pull-up resistors must be connected to the positive supply voltage.

Interface protocol

The format consists of the following

‧A START condition

‧A chip address byte including the MS6260 address. (7bits)

‧The 8th bit of the byte must be “0”.(write=0, read=1)

‧The MS6260 must always acknowledge the end of each transmitted byte.

‧A data sequence (N-bytes + Acknowledge)

‧A STOP condition
