666 * Values for the BitRate Register (SCBRR)
668 * The values are actually divisors for a frequency which can
669 * be internal to the SH3 (14.7456MHz) or derived from an external
670 * clock source. This driver assumes the internal clock is used;
671 * to support using an external clock source, config options or
672 * possibly command-line options would need to be added.
674 * Also, to support speeds below 2400 (why?) the lower 2 bits of
675 * the SCSMR register would also need to be set to non-zero values.
677 * -- Greg Banks 27Feb2000
679 * Answer: The SCBRR register is only eight bits, and the value in
680 * it gets larger with lower baud rates. At around 2400 (depending on
681 * the peripherial module clock) you run out of bits. However the
682 * lower two bits of SCSMR allow the module clock to be divided down,
683 * scaling the value which is needed in SCBRR.
685 * -- Stuart Menefy - 23 May 2000
687 * I meant, why would anyone bother with bitrates below 2400.
