755 * Values for the BitRate Register (SCBRR)
757 * The values are actually divisors for a frequency which can
758 * be internal to the SH3 (14.7456MHz) or derived from an external
759 * clock source. This driver assumes the internal clock is used;
760 * to support using an external clock source, config options or
761 * possibly command-line options would need to be added.
763 * Also, to support speeds below 2400 (why?) the lower 2 bits of
764 * the SCSMR register would also need to be set to non-zero values.
766 * -- Greg Banks 27Feb2000
768 * Answer: The SCBRR register is only eight bits, and the value in
769 * it gets larger with lower baud rates. At around 2400 (depending on
770 * the peripherial module clock) you run out of bits. However the
771 * lower two bits of SCSMR allow the module clock to be divided down,
772 * scaling the value which is needed in SCBRR.
774 * -- Stuart Menefy - 23 May 2000
776 * I meant, why would anyone bother with bitrates below 2400.
