4.7
This section contains the AC electrical information (including timing specifications) for different modules
of the MCIMX35. The modules are listed in alphabetical order.
4.7.1
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.
4.7.2
The MCIMX35 provides two CSPI modules. CSPI ports are multiplexed in the MCIMX35 with other
pads. See the IOMUX chapter of the reference manual for more details.
