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