Notes
1. The crystal frequencies 22.5792 MHz
±200 × 106 MHz and 24.5760 MHz ±200 × 106 MHz must track each other
in frequency with an accuracy of 200
× 106 MHz. For example if the 24.5760 MHz clock is 150 × 106 MHz fast, then
the range of the 22.5792 MHz clock becomes
50 × 106 MHz and +350 × 106 MHz
2. Timing values only valid for internally generated FS256.
