Notes:
12. After powering-up the CS42516, RST
should be held low after the power supplies and clocks are set-
tled.
13. See Table 1 on page 25 for suggested OMCK frequencies
14. Limit the loading on RMCK to 1 CMOS load if operating above 24.576 MHz.
15. Not valid when RMCK_DIV in “Clock Control (address 06h)” on page 52 is set to Multiply by 2.
16. 76.5 ns for Single-Speed and Double-Speed modes, 23 ns for Quad-Speed Mode.
