clock is output to the outside on the SCK pin. The SCK pin becomes a high level
when data transfer starts. When writing (in the transmit mode) or reading (in the
receive mode) data cannot follow the serial 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 complete.
ensure shift operation, a pulse width of at least 4 machine cycles is required for
both high and low levels in the serial clock. The maximum data transfer frequency
is 625 kHz (at fc = 20 MHz).
