SSI Timing Parameters

This section describes the timing parameters of the SSI module. The connectivity of the serial

synchronous interfaces are summarized in Table 82.

NOTE

•

The terms WL and BL used in the timing diagrams and tables refer to

Word Length (WL) and Bit Length (BL).

•

The SSI timing diagrams use generic signal names wherein the names

used in the i.MX53 Reference Manual are channel specific signal

names. For example, a channel clock referenced in the IOMUXC

chapter as AUD3_TXC appears in the timing diagram as TXC.
