Module-Level AC Electrical Specifications
This section contains the AC electrical information (including timing specifications) for the modules of
the i.MX35. The modules are listed in alphabetical order.
4.9.1
AUDMUX Electrical Specifications
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. See the electrical specification for SSI.
4.9.2
CSPI AC Electrical Specifications
The i.MX35 provides two CSPI modules. CSPI ports are multiplexed in the i.MX35 with other pins. See
the “External Signals and Multiplexing” chapter of the reference manual for more details.
