1. Timing numbers are based on default LVCMOS 3.3 I/O Buffers. Use timing adjusters provided to calculate timing for other standards.
2. Measured using standard switching circuit, assuming segment and global routing loading of 1, worst case PTSA loading and 1 output
3. Pulse widths and clock widths less than minimum will cause unknown behavior.
4. Standard 16-bit counter using SRP feedback.
