Timing parameters for UDMA out-bursts are listed in Table 40.
3.7.3
Digital Audio Mux (AUDMUX) Timing
The AUDMUX provides a programmable interconnect logic for voice, audio, and data routing between
internal serial interfaces (SSI and SAP) and external serial interfaces (audio and voice codecs). The AC
timing of AUDMUX external pins is governed by the SSI modules. For more information, see
3.7.4
CMOS Sensor Interface (CSI) Timing
The CSI enables the chip to connect directly to external CMOS image sensors, which are classified as
dumb or smart as follows:
Dumb sensors only support traditional sensor timing (vertical sync (VSYNC) and horizontal sync
(HSYNC)) and output-only Bayer and statistics data.
Smart sensors support CCIR656 video decoder formats and perform additional processing of the
image (for example, image compression, image pre-filtering, and various data output formats).
The following subsections describe the CSI timing in gated and ungated clock modes.
