Electrical Characteristics
4.9
The following sections provide information on external peripheral interfaces.
4.9.1
The AUDMUX provides programmable interconnect logic for voice, audio and data routing between
internal serial interfaces (SSIs) and external serial interfaces (audio and voice codecs). The AC timing of
AUDMUX external pins is hence governed by the SSI module.
4.9.2
This section describes the timing parameters of the CSPI and eCSPI modules. The CSPI and eCSPI have
separate timing parameters for master and slave modes. The nomenclature used with the CSPI/eCSPI
modules and the respective routing of these signals is shown in
