; extract the immediate value by locating it using the PC)
Breakpoint.
where:
imm
The BKPT instruction causes the processor to enter Debug state. Debug tools can use this to
investigate system state when the instruction at a particular address is reached.
imm is ignored by the processor. If required, a debugger can use it to store additional informa-
tion about the breakpoint.
The BKPT instruction can be placed inside an IT block, but it executes unconditionally, unaf-
fected by the condition specified by the IT instruction.
This instruction does not change the flags.
BKPT #imm
is an expression evaluating to an integer in the range 0-255 (8-bit value).
