670 * Values for the BitRate Register (SCBRR)
672 * The values are actually divisors for a frequency which can
673 * be internal to the SH3 (14.7456MHz) or derived from an external
674 * clock source. This driver assumes the internal clock is used;
675 * to support using an external clock source, config options or
676 * possibly command-line options would need to be added.
678 * Also, to support speeds below 2400 (why?) the lower 2 bits of
679 * the SCSMR register would also need to be set to non-zero values.
681 * -- Greg Banks 27Feb2000
683 * Answer: The SCBRR register is only eight bits, and the value in
684 * it gets larger with lower baud rates. At around 2400 (depending on
685 * the peripherial module clock) you run out of bits. However the
686 * lower two bits of SCSMR allow the module clock to be divided down,
687 * scaling the value which is needed in SCBRR.
689 * -- Stuart Menefy - 23 May 2000
691 * I meant, why would anyone bother with bitrates below 2400.
693 * -- Greg Banks - 7Jul2000
695 * You "speedist"! How will I use my 110bps ASR-33 teletype with paper
696 * tape reader as a console!
