CPU-generated - BREAKPOINT

Desc: Generated by the one-byte breakpoint instruction (opcode CCh)

Notes: Used by debuggers to implement breakpoints, such as MS-DOS DEBUG's G command. Also used by Turbo Pascal versions 1,2,3 when {$U+} specified. Return address points to byte following the breakpoint instruction. Called by Novell DOS 7 EMM386 after displaying an exception error message (GPF, illegal opcodes, etc.) and before waiting for user input. Called by QEMM-386 if the user presses 'I' (undocumented) when prompted after an exception error message
