Peripheral operating requirements and behaviors
6.4.2 EzPort Switching Specifications
6.4.3 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.
