Figure 15-12 Termination of Data Transfer in Master Receiver Mode
In the slave mode, a serial bus interface circuit operates either in normal slave mode or in slave mode after
In the slave mode, the conditions of generating INTSBI interrupt request are follows:
When the MST is “0” (Slave mode)
outputs a clock pulse for 1-word of data transfer and the acknowledge signal each time that received
data is read from the SBIDBR.
before the last data to be received. A serial bus interface circuit does not generate a clock pulse for the
acknowledge signal by clearing ACK. In the interrupt routine of end of transmission, when the BC is
set to “001” and read the data, PIN is set to “1” and generates a clock pulse for a 1-bit data transfer. In
this case, since the master device is a receiver, the SDA line on a bus keeps the high-level. The transmitter
receives the high-level signal as an ACK signal. The receiver indicates to the transmitter that data transfer
is complete.
