90 * Time constant routines follow. See SBK, section 12.
91 * Although they don't come out and say it (in the docs),
92 * the card clearly uses a 1MHz countdown timer, as the
93 * low-speed formula (p. 12-4) is:
94 * tc = 256 - 10^6 / sr
95 * In high-speed mode, the constant is the upper byte of a 16-bit counter,
96 * and a 256MHz clock is used:
97 * tc = 65536 - 256 * 10^ 6 / sr
98 * Since we can only use the upper byte of the HS TC, the two formulae
99 * are equivalent. (Why didn't they say so?) E.g.,
100 * (65536 - 256 * 10 ^ 6 / x) >> 8 = 256 - 10^6 / x
101 *
102 * The crossover point (from low- to high-speed modes) is different
103 * for the SBPRO and SB20. The table on p. 12-5 gives the following data:
104 *
105 * SBPRO SB20
106 * ----- --------

90 * Time constant routines follow. See SBK, section 12.
91 * Although they don't come out and say it (in the docs),
92 * the card clearly uses a 1MHz countdown timer, as the
93 * low-speed formula (p. 12-4) is:
94 * tc = 256 - 10^6 / sr
95 * In high-speed mode, the constant is the upper byte of a 16-bit counter,
96 * and a 256MHz clock is used:
97 * tc = 65536 - 256 * 10^ 6 / sr
98 * Since we can only use the upper byte of the HS TC, the two formulae
99 * are equivalent. (Why didn't they say so?) E.g.,
100 * (65536 - 256 * 10 ^ 6 / x) >> 8 = 256 - 10^6 / x
101 *
102 * The crossover point (from low- to high-speed modes) is different
103 * for the SBPRO and SB20. The table on p. 12-5 gives the following data:
104 *
105 * SBPRO SB20
