High width of the WS signal to become longer by one I2SnCK0 pulse than the Low width.

Based on the above, the transfer clock is set to 400 kbps, and the sampling frequency is
set to 8 kHz in this example.

LSI. Setting I2S0CTL<SYSKE0>=1 and I2S0CTL<CNTE0>=1 enables the WS
signal to be sent to the AD converter. This can be done regardless of the setting of
I2S0CTL<TXE0>.
