Read Revision (
On-Chip Debugger. If OCD commands are added, removed, or changed, this revision
number changes.
Write OCD Counter Register (
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 Read OCD Status Register command reads the
OCDSTAT register.
Read OCD Counter Register (
count system clock cycles in between Breakpoints, generate a BRK when it counts
down to 0, or generate a BRK when its value matches the Program Counter. Because
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
Write OCD Control Register (
writes the data that follows to the OCDCTL register.
