Description of SCK Pin
The SCK pin is not used.
The SCK pin functions as an input
pin
(Input signals are ignored).
(Initial value)
The SCK pin outputs the clock
(with a frequency 16 times the bit
rate).
The SCK pin inputs the clock
(with a frequency 16 times the bit
rate).
When SC_CLK is selected, the
SCK pin inputs the clock (Input
signals are ignored).
Set the SCK input or SC_CLK so
that the frequency of BRGCLK is
16 times the bit rate.
When selecting SC_CLK, set the
frequency of SC_CLK and DL, or
when selecting SCK, adjust the
frequency of the SCK input to
make the frequency of BRGCLK
16 times the bit rate.
—
The SCK pin outputs the
synchronization clock.
The SCK pin outputs the
synchronization clock.
