7.1. HMON
7.1.1. M
The HMON library is built to support Normal Mode only.
7.1.2. B
The monitor utilises the Address Break Controller for code located in ROM, allowing a single breakpoint to be set in the code.
Code located in RAM may have multiple breakpoints limited only by the size of the On-Chip RAM.
Due to a limitation of the internal address break controller, a breakpoint set in ROM will execute the instruction at the
breakpoint and stop on the subsequent op-code.
Double clicking in the breakpoint column in the code sets the breakpoint. Adding a further breakpoint in the code removes
the previous one. A warning message will be displayed in the message window when this occurs.
Double clicking in the breakpoint column in the code sets the breakpoint. Breakpoints will remain unless they are double
clicked to remove them.
7.1.3. H
HMON is built along with the debug code. Certain elements of the HMON code must remain at a fixed location in memory.
The following table details the HMON components and their size and location in memory. For more information, refer to the
map file when building code.
* CUserVectors is a long word location with the upper 16 bits set to zero.

FDT User Mode Kernel.
This is at a fixed location and must not be moved. Should the
kernel need to be moved it must be re-compiled.
