Peripheral operating requirements and behaviors
6.4.4 Flexbus Switching Specifications
All processor bus timings are synchronous; input setup/hold and output delay are given in
respect to the rising edge of a reference clock, FB_CLK. The FB_CLK frequency may be
the same as the internal system bus frequency or an integer divider of that frequency.
The following timing numbers indicate when data is latched or driven onto the external
bus, relative to the Flexbus output clock (FB_CLK). All other timing relationships can be
derived from these values.
