Debug Command

Reserved
In the following bulleted list of OCD Commands, data and commands sent from the host to
the OCD are identified by ’DBG ← Command/Data’. Data sent from the OCD back to the
host is identified by ’DBG → Data’
•

•
Read OCD Revision (00H)
version of the OCD. If OCD commands are added, removed, or changed, this revision
number changes.
Write OCD Counter Register (01H)
writes the data that follows to the OCDCNTR register. If the device is not in DEBUG
mode, the data is discarded.
Read OCD Status Register (02H)
the OCDSTAT register.
Read OCD Counter Register (03H)
count system clock cycles in between Breakpoints, generate a BRK when it counts
down to zero, or generate a BRK when its value matches the Program Counter. Since
this register is really a down counter, the returned value is inverted when this register
is read so the returned result appears to be an up counter. If the device is not in
DEBUG mode, this command returns FFFFH.
Write OCD Control Register (04H)
writes the data that follows to the OCDCTL register. When the Read Protect Option
Bit is enabled, the DBGMODE bit (OCDCTL[7]) can only be set to 1, it cannot be
cleared to 0 and the only method of putting the device back into normal operating
mode is to reset the device.
