New Instructions
The debugger’s Disassembler supports the 3 new instructions in the COP8 flash devices (BRK, JSRB and RETF):
However, the Single-Line Assembler does not support them.
If you do “patch in” a BRK instruction (by changing the value in a code memory location to 0x62), the emulator will
break (stop emulating) when the COP8 processor executes the BRK instruction at that location. However, in such a
case, the software will issue the following diagnostic:
because the debugger did not set the break-point in the “normal” manner. (See the Operational Considerations chapter.)
If you try to execute a RETF instruction in program code flash memory, it will behave exactly like a RET instruction,
per the NSC device specification.
Unsolicited breakpoint encountered at 0xhhhh.
(The program contains a non-breakpoint BRK instruction.)
