Multifunction Pins
Table 7 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)
S(1): The MCLK pin can be used to drive the PLL and Codec Clock inputs simultaneously
(2)
S(2): The BCLK pin can be used to drive the PLL and Codec Clock and audio interface bit clock inputs simultaneously
(3)
S(4): The GPIO/MFP5 pin can be used to drive the PLL and Codec Clock inputs simultaneously
(4)
D: Default Function
(5)
E: The pin is exclusively used for this function, no other function can be implemented with the same pin (e.g. if GPIO/MFP5 has been
allocated for General Purpose Output, it cannot be used as the INT1 output at the same time)
Analog Audio I/O
The analog I/O path of the TLV320AIC3253 offers a variety of options for signal conditioning and routing:
2 headphone amplifier outputs
Analog gain setting
Single ended and differential modes
