Description
No operation, or cancel current operation
Calculate CRC of memory area
Write trace data from debug system to memory
Reserved
Description
Overwrite old buffer contents
Disable nanotrace
Make the CPU enter debug mode, but stop CPU until place has been freed for the last few trace
frames.
Note: This may deadlock self-hosted debuggers!
Make the CPU enter debug mode, and flush the last few trace frames that don’t fit in the buffer.
