ginning or finishing of a transfer, SCK pin is kept in high level.
al clock rate, an automatic-wait function is executed to stop the serial clock automatically and hold
the next shift operation until reading or writing is completed (shown in "Figure 10-2 Automatic-
wait Function (Example of transmit mode)"). The maximum time from releasing the automatic-wait
function by reading or writing a data is 1 cycle of the selected serial clock until the serial clock
comes out from SCK pin.
