Asynchronous mode
Asynchronous mode
Clocked synchronous mode
The SCK pin can be used as an I/O port pin.
The SCK pin outputs a clock with the same
frequency as the bit rate.
A clock with a frequency 16 times the bit rate should
be input from the SCK pin.
Clocked synchronous mode
The SCK pin functions as a clock output pin.
The SCK pin functions as a clock input pin.
The SCK pin can be used as an I/O port pin.
The SCK pin outputs a clock with the same
frequency as the bit rate.
 When using an external clock, a clock with a
