Electrical Characteristics
4.3.6
The AUDMUX provides a programmable interconnect logic for voice, audio and data routing between
internal serial interfaces (SSI) and external serial interfaces (audio and voice codecs). The AC timing of
AUDMUX external pins is hence governed by the SSI module. Please refer to their respective electrical
specifications.
