17.6.2 Addresses
the master device via bus lines. Therefore, each slave device connected via the bus lines must have a unique
address.
data matches the data values stored in the SVA0 register. If the address data matches the SVA0 values, the slave
device is selected and communicates with the master device until the master device generates a start condition or
stop condition.
direction specification below, are together written to the IIC0 register and are then output. Received addresses are
written to the IIC0 register.
The 7 bits of data that follow the start condition are defined as an address.
An address is a 7-bit data segment that is output in order to select one of the slave devices that are connected to
The slave devices include hardware that detects the start condition and checks whether or not the 7-bit address
Note The interrupt request signal (INTIIC) is generated if a local address or extension code is received during
