721 * Values for the BitRate Register (SCBRR)
723 * The values are actually divisors for a frequency which can
724 * be internal to the SH3 (14.7456MHz) or derived from an external
725 * clock source. This driver assumes the internal clock is used;
726 * to support using an external clock source, config options or
727 * possibly command-line options would need to be added.
729 * Also, to support speeds below 2400 (why?) the lower 2 bits of
730 * the SCSMR register would also need to be set to non-zero values.
732 * -- Greg Banks 27Feb2000
734 * Answer: The SCBRR register is only eight bits, and the value in
735 * it gets larger with lower baud rates. At around 2400 (depending on
736 * the peripherial module clock) you run out of bits. However the
737 * lower two bits of SCSMR allow the module clock to be divided down,
738 * scaling the value which is needed in SCBRR.
740 * -- Stuart Menefy - 23 May 2000
742 * I meant, why would anyone bother with bitrates below 2400.
744 * -- Greg Banks - 7Jul2000

747 * tape reader as a console!
