7.4.3 Multifunction Pins

Table 7-1 shows the possible allocation of pins for specific functions. The PLL input, for example, can be programmed to be any of 4 pins (MCLK, BCLK, DIN, GPIO).

(1) E: The pin is exclusively used for this function, no other function can be implemented with the same pin. (If GPIO/DOUT has been allocated for General Purpose Output, it cannot be used as the INT1 output at the same time.)
(2) S(1): The MCLK pin can drive the PLL and Codec Clock inputs simultaneously.
(3) S(2): The BCLK pin can drive the PLL and Codec Clock and audio interface bit clock inputs simultaneously.
(4) S(3): The GPIO/DOUT pin can drive the PLL and Codec Clock inputs simultaneously.
(5) D: Default Function
