MC9S08PA..Code for Delay routine

[mikee_]

Hello,

I am writing this piece of code in order to insert a delay in my execution cycle.

The code is the following:

DELAY:                STHX    DLY_A  ; (4)

LOOPOUT:          STX     DLY_B  ; (3)

LOOPIN:    

                             DEC     DLY_B  ; (4)

                             BNE     LOOPIN ; (3)

                             DEC     DLY_A  ; (4)

                             BNE     LOOPOUT ;(3)

                             RTS

I am using code warrior 10.6

After starting the debug process. The communication with the micro-controller will stop after debugger will step in and is able to do few iterations .

PS: watchdog is deactivated.

Looks really weird.

Any help?

Any body has a better way to insert delay?

Many thanks

Hard to tell what's wrong without more complete code.  For example, where are DLY_A and DLY_B variables located?

BTW, here's a sample delay routine to give you an idea (but for ASM8 assembler)
