Description
Slave Address
These bits are the address of the slave which
the master communicates with.
Slave Transfer Mode
This bit specifies the mode in which the slave
operates.
Bit STM1 sets the operating mode (transmit or
receive mode) of the slave, which is an
external slave device whose address matches
the slave address (SADD1) sent from the
master. The slave device is automatically set to
transmit/receive mode by hardware on
reception of the STM1 signal.
When this bit is set to 1, it indicates a read
operation, when this bit is cleared to 0, it
indicates a write operation.
