1. Timing numbers are based on default LVCMOS 1.8 I/O buffers. Use timing adjusters provided to calculate other standards.
Timing v.3.2
2. Measured using standard switching circuit, assuming GRP loading of 1 and 1 output switching.
3. Pulse widths and clock widths less than minimum will cause unknown behavior.
4. Standard 16-bit counter using GRP feedback.
