736 | * Values for the BitRate Register (SCBRR) | |
737 | * | |
738 | * The values are actually divisors for a frequency which can | |
739 | * be internal to the SH3 (14.7456MHz) or derived from an external | |
740 | * clock source. This driver assumes the internal clock is used; | |
741 | * to support using an external clock source, config options or | |
742 | * possibly command-line options would need to be added. | |
743 | * | |
744 | * Also, to support speeds below 2400 (why?) the lower 2 bits of | |
745 | * the SCSMR register would also need to be set to non-zero values. | |
746 | * | |
747 | * -- Greg Banks 27Feb2000 | |
748 | * | |
749 | * Answer: The SCBRR register is only eight bits, and the value in | |
750 | * it gets larger with lower baud rates. At around 2400 (depending on | |
751 | * the peripherial module clock) you run out of bits. However the | |
752 | * lower two bits of SCSMR allow the module clock to be divided down, | |
753 | * scaling the value which is needed in SCBRR. | |
754 | * | |
755 | * -- Stuart Menefy - 23 May 2000 | |
756 | * | |
757 | * I meant, why would anyone bother with bitrates below 2400. | |
