Wow...great stuf - thanks.

you'll be pleased to hear it's bedtime here in the UK, so radio silence falls upon this thread!

You've been a great help, in closing re the IOC interupt config ....we were both wrong - I think (...though you were only one character out - I was way out!), the correct IOC config might be like this...???

Code:
ASM
INT_LIST  macro    ; IntSource,        Label,  Type, ResetFlag?
        INT_Handler   RBC_INT,  _ToggleLED1,   PBP,  yes
    endm
    INT_CREATE               ; Creates the interrupt processor
ENDASM

@ INT_ENABLE  RBC_INT     ; enable IOC interrupts
