Clock source
In the internal clock mode, one of the seven frequencies can be selected as a serial
clock, which is output to the outside through the SCK pin. At the beginning of a
transfer, the SCK pin output becomes the “H” level.
If the program cannot keep up with this serial clock rate in writing the transmit data or
reading the received data, the SBI automatically enters a wait period. During this
period, the serial clock is stopped automatically and the next shift operation is
suspended until the processing is completed.
The SBI uses an external clock supplied from the outside to the SCK pin as a serial
clock. For proper shift operations, the serial clock at the “H” and “L” levels must have
the pulse widths as shown below.
Internal or external clocks can be selected by programming SBIxCR1 <SCK2:0>.
