.def _DSP28x_usDelay

;====================================================

;Delay Function 

;The C assembly call will look as follows: 

;

;  extern void Delay(long time);                

;        MOV   AL,#LowLoopCount

;        MOV   AH,#HighLoopCount

;        LCR   _Delay

;

;Or as follows (if count is less then 16-bits):

;

;        MOV   ACC,#LoopCount

;        LCR   _Delay

        .global  __DSP28x_usDelay

_DSP28x_usDelay:

        SUB    ACC,#1

        NOP

        NOP

        BF     _DSP28x_usDelay,GEQ    ;; Loop if ACC >= 0

        LRETR 

;There is a 9/10 cycle overhead and each loop

;takes five cycles. The LoopCount is given by

;the following formula:

;  DELAY_CPU_CYLES = 9 + 5*LoopCount

; LoopCount = (DELAY_CPU_CYCLES - 9) / 5
