DSP56305 Errata  1996 - 2002 Motorola pg. 20 /ng/12/20/02
ES89
Description (added 6/25/98):
If the SCI Receiver is programmed to work with a different serial clock
than the SCI Transmitter so that either the Receiver or Transmitter is
using the external serial clock and the other is using the internally-
generated serial clock—RCM and TCM in the SCCR are programmed
differently)—then the internal serial clock generator will not operate and
the SCI portion (Receiver or Transmitter) clocked by the internal clock
will be stuck.
Workaround:
Do not use SCI with the two SCI portions (Receiver and Transmitter)
clocked by different serial clocks; use either both externally or both
internally clocked.
Or:
When using both portions of the SCI (Receiver & Transmitter), do not
program different values on RCM and TCM in the SCCR.
