1. Values can be obtained from the following equations, according to BCLK frequency.
2. Values can be obtained from the following equations, according to BCLK frequency and external bus cycles.
(if external bus cycle is a
φ + bφ, n=(bx2)-1)

(if external bus cycle is a
φ + bφ, m= b)
NOTES:
3. tc ns is added when recovery cycle is inserted.
