695 * Values for the BitRate Register (SCBRR)
697 * The values are actually divisors for a frequency which can
698 * be internal to the SH3 (14.7456MHz) or derived from an external
699 * clock source. This driver assumes the internal clock is used;
700 * to support using an external clock source, config options or
701 * possibly command-line options would need to be added.
703 * Also, to support speeds below 2400 (why?) the lower 2 bits of
704 * the SCSMR register would also need to be set to non-zero values.
706 * -- Greg Banks 27Feb2000
708 * Answer: The SCBRR register is only eight bits, and the value in
709 * it gets larger with lower baud rates. At around 2400 (depending on
710 * the peripherial module clock) you run out of bits. However the
711 * lower two bits of SCSMR allow the module clock to be divided down,
712 * scaling the value which is needed in SCBRR.
714 * -- Stuart Menefy - 23 May 2000
716 * I meant, why would anyone bother with bitrates below 2400.

721 * tape reader as a console!
