3.10.1 BKPT
Breakpoint.
3.10.1.1 Syntax
BKPT #imm
where:
imm
is an expression evaluating to an integer in the range 0-255 (8-bit value).
3.10.1.2 Operation
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 information about
the breakpoint.
The BKPT instruction can be placed inside an IT block, but it executes unconditionally, unaffected by
the condition specified by the IT instruction.
3.10.1.3 Condition flags
This instruction does not change the flags.
3.10.1.4 Examples
BKPT 0xAB
; Breakpoint with immediate value set to 0xAB (debugger can
; extract the immediate value by locating it using the PC)
3.10.2 CPS
Change Processor State.
3.10.2.1 Syntax
