OCD Serial Errors
datastreams, the maximum recommended baud rate is the system clock frequency divided
by eight. The maximum possible baud rate for asynchronous datastreams is the system
clock frequency divided by four, but this theoretical maximum is possible only for low
noise designs with clean signals.
baud rates for sample crystal frequencies.
Table 98. OCD Baud-Rate Limits
If the OCD receives a Serial Break (nine or more continuous bits Low) the auto-baud
detector/generator resets. Reconfigure the auto-baud detector/generator by sending
The OCD detects any of the following error conditions on the DBG pin:
•
•
•
When the OCD detects one of these errors, it aborts any command currently in progress,
transmits a four character long Serial Break back to the host, and resets the auto-baud
detector/generator. A Framing Error or Transmit Collision may be caused by the host
sending a Serial Break to the OCD. Because of the open-drain nature of the interface,
returning a Serial Break break back to the host only extends the length of the Serial Break
if the host releases the Serial Break early.
The host transmits a Serial Break on the
XP F0823 Series devices or when recovering from an error. A Serial Break from the host
resets the auto-baud generator/detector but does not reset the OCD Control register. A
Serial Break leaves the device in DEBUG mode if that is the current mode. The OCD is
held in Reset until the end of the Serial Break when the DBG pin returns High. Because of
the open-drain nature of the DBG pin, the host sends a Serial Break to the OCD even if the
OCD is transmitting a character.
