11.3.1.6 Timing in Clock Type 1 Slave Mode
The operation is fundamentally performed in the same timing in both the master and slave modes. In the clock type 1
slave mode, in order for it to be able to perform any time when the clock is supplied from the master, preparation for data
transfer that follows is started as soon as the preceding data transfer is completed.
Figure 11-11 shows the transmission/reception operation waveform (with 8-bit length, clock type 1) of the synchronous
serial port.

[Note]
Ÿ
Even after the start interrupt has been generated, it is possible to write data to the transfer buffer before
the transfer is actually started (before the external clock is supplied). In that case, the data written just
before the start of the transfer is transferred.
Ÿ
To ensure that data is successfully transmitted, it is recommended that data is written when SnEN is "0"
or while the transfer of previous data is in progress (SnTXF=1).
