DT USB Flags

[pedja089]

That is ASM syntax.
DEFINE's are just passed to LST file, after compile.
There is no direct connection between that two pice of code.
LED's are turned on/off with macro's in DT_HID260.pbp
MACROs for LED:

ASM
    ifndef  USB_LEDPOLARITY          ; If LED polarity wasn't specified?
USB_LEDPOLARITY = 1                  ;   default to ON when HIGH
    endif
    
;-------------------------------     
LEDOFF  macro Port, Bit              ; -- Turn LED OFF --
    if (USB_LEDPOLARITY == 1)        ;   If LED is ON when HIGH?
        LOW?T  Port, Bit             ;     make it LOW
    else                             ;   otherwise
        HIGH?T Port, Bit             ;     make it HIGH
    endif
  endm

;-------------------------------  
LEDON  macro Port,Bit                ; -- Turn LED ON --
    if (USB_LEDPOLARITY == 1)        ;   If LED is ON when HIGH?
        HIGH?T Port, Bit             ;     make it HIGH
    else                             ;   otherwise
        LOW?T  Port, Bit             ;     make it LOW
    endif
  endm

;-------------------------------  
ifLEDisON  macro Port,Bit, Label
    if (USB_LEDPOLARITY == 1)        ; if LED is ON when HIGH
        btfsc   Port, Bit            ;   and the pin is LOW
    else                             ; or if LED is ON when LOW
        btfss   Port, Bit            ;   and the pin is HIGH
    endif                            ; then the LED is OFF
    goto      Label                  ;    so don't jump to the label
  endm                                       
;-------------------------------  
ifLEDisOFF  macro Port,Bit, Label
    if (USB_LEDPOLARITY == 1)        ; if LED is ON when HIGH
        btfss   Port, Bit            ;   and the pin is HIGH
    else                             ; or if LED is ON when LOW
        btfsc   Port, Bit            ;   and the pin is LOW
    endif                            ; then the LED is ON
    goto      Label                  ;    so don't jump to the label
  endm  
ENDASM

As you can see from macros, Darrel used HIGH and LOW commands from PBP to handle BANK, TRIS, and output register of port.

To turn TX LED:

;----[Send USB data]--------------------------------------------------------
DoUSBOut:
    ASM
        ifdef    USB_TXLED
            LEDON  USB_TXLED
        endif  
    ENDASM
....

He call LED macro from DoUSBOut subrutine...

DoUSBService:
    INTS_FROM = INTS_FROM | UIR
ASM
   ifdef USB_ServiceLED
     LEDON  USB_ServiceLED
   endif
ENDASM

etc...

Argh, I had looked for FLAG in the include.

And I just noticed I can't rename those as I wish either, ooops.
