be done by setting the transmit acknowledge bit (TXAK) before reading
the 2nd last byte of data. Before reading the last byte of data, a STOP
signal must be generated first. The following is an example showing how
a STOP signal is generated by a master receiver.
At the end of data transfer, if the master still wants to communicate on
the bus, it can generate another START signal followed by another slave
address without first generating a STOP signal. A program example is
as shown.
In the slave interrupt service routine, the module addressed as slave bit
(IAAS) should be tested to check if a calling of its own address has just
been received (see
transmit/receive mode select bit (Tx/Rx bit of IBCR) according to the
R/W command bit (SRW). Writing to the IBCR clears the IAAS
automatically. Note that the only time IAAS is read as set is from the
interrupt at the end of the address cycle where an address match
occurred, interrupts resulting from subsequent data transfers will have
IAAS cleared. A data transfer may now be initiated by writing information
to IBDR, for slave transmits, or dummy reading from IBDR, in slave
