2. Asynchronous Mode: ASYNC bit = “1”, PSEL = “0”
When ASYNC bit is “1”, DIT and DIR can operate at different sample rates(non-multiples). In Mode1, Mode2 (When
the PLL is the unlock state) and Mode3, SDTO is fixed “L”. The input timing of DAUX should be synchronized with
ELRCK and EBCIK. The master clock of TX can be selected to either X’tal or EMCK by the MSEL bit (See Table 4).
Note 18. ON: Oscillation (Power-up), OFF: STOP (Power-down)
Note 19 When the X’tal is not used as clock comparison for sampling frequency detection (i.e. XTL1,0 = “1,1”), the
