14.5.2 Addresses
the master device via the bus lines. Therefore, each slave device connected via the bus lines must have a unique
address.
data matches the data values stored in the slave address register (SVA). If the address data matches the SVA values,
the slave device is selected and communicates with the master device until the master device generates a start
condition or stop condition.
14.5.3 Transfer direction specification are written to the IICA shift register (IICA). The received addresses are
written to IICA.
14.5.3 Transfer direction specification
data to a slave device. When the transfer direction specification bit has a value of “1”, it indicates that the master
device is receiving data from a slave device.
The address is defined by the 7 bits of data that follow the start condition.
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 INTIICA is not issued if data other than a local address or extension code is received during slave device
Addresses are output when a total of 8 bits consisting of the slave address and the transfer direction described in
The slave address is assigned to the higher 7 bits of IICA.
In addition to the 7-bit address data, the master device sends 1 bit that specifies the transfer direction.
When this transfer direction specification bit has a value of “0”, it indicates that the master device is transmitting
Note INTIICA is not issued if data other than a local address or extension code is received during slave device
operation.
