Figure 7-8 shows an example of passive mode output with 8-bit word size selected via the sioc OLEN field (bit 1).
The overall pipelining between successive words is the same as for 16-bit mode. Because the active mode ILD
and OLD generators can only be set to ICK or OCK ÷ 16, active mode input and output in an 8-bit mode will proba-
bly not be used.
