The acknowledge bit may indicate specific events such as completion of receive data processing
for some receiving devices, and for other receiving devices, the acknowledge bit may be held to 1,
indicating no specific events.
The I
the slave address and the R/W bit, confirmation of reception with the acknowledge bit, indication
of the last frame, and so on. Therefore, continuous data transfer using the DTC must be carried out
in conjunction with CPU processing by means of interrupts.
Table 15.9 shows some examples of processing using the DTC. These examples assume that the
number of transfer data bytes is known in slave mode.
