1. 20 MHz is the maximum input frequency when using an external crystal oscillator; however, 40 MHz can be
2. If wait states are used, add 2t
3. Assuming back-to-back bus cycles.
4. When forcing wait states using the BUSCON register, add 2t
5. Exceeding the maximum specification causes additional wait states.
6. 8-bit bus only.
7. The first falling edge of READY is not synchronized to a CLKOUT edge; therefore, one programmed wait
8. Device is static by design but has been tested only down to 20 MHz.
9. Assumes CLKOUT is operating in divide-by-two mode (f/2).
