128  * Time constant routines follow.  See SBK, section 12.
129  * Although they don't come out and say it (in the docs),
130  * the card clearly uses a 1MHz countdown timer, as the
131  * low-speed formula (p. 12-4) is:
132  *        tc = 256 - 10^6 / sr
133  * In high-speed mode, the constant is the upper byte of a 16-bit counter,
134  * and a 256MHz clock is used:
135  *        tc = 65536 - 256 * 10^ 6 / sr
136  * Since we can only use the upper byte of the HS TC, the two formulae
137  * are equivalent.  (Why didn't they say so?)  E.g.,
138  *        (65536 - 256 * 10 ^ 6 / x) >> 8 = 256 - 10^6 / x
139  *
140  * The crossover point (from low- to high-speed modes) is different
141  * for the SBPRO and SB20.  The table on p. 12-5 gives the following data:
