8-4-1: XINSEL = 0 setting, 12.288MHz must be set when calculating input sampling frequency
8-4-2: XINSEL =1 setting, 24.576MHz must be set when calculating input sampling frequency
8-4-3: When RMCK and SBCK source clocks are identical
8-4-4: When SBCK is the PLL source clock
8-4-5: TCKSEL = 0 setting (256fs), the falling edge of TBCK is in synchronization with the rising edge of TMCK.
TCKSEL = 1 setting (128fs), the falling edge of TBCK is in synchronization with the falling edge of TMCK.
