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

||||
* -- Greg Banks - 7Jul2000

|
||||
* tape reader as a console!
