Posted on May 17, 2011 at 15:05The following code shows a strange HALT instruction behaviour:
Code:
HALT_MCU
HALT
JRA HALT_MCU
Its meaning is simple: if something wakes up the STM8 core, the jump forces it to halt again.
When I debug my code with STVD7, the jump instruction is ignored.
To have the intended behaviour, I have to modify the code as:
Code:
HALT_MCU
HALT
NOP
NOP
JRA HALT_MCU
Why?

PS: I'm debugging a STM8S207C8 with R-Link
