Assembly Command Clarification

threadz

While reading through the assembly command list I noticed the REP command and got curious about its limitations.
Specifically, can one REP command contain another like in this example code for driving a neopixel:

rep     #12,          %[pixel_cnt]
rdlong  %[thisPixel], %[hubPtr]
add     %[hubPtr],    #4              
mov     %[bit],       #8            

rep     #8,           #24             
drvh    %[pixel_pin]                  
testb   %[thisPixel], %[bit]       WC
incmod  %[bit],       #32         
waitx   %[tickH]                     
drvc    %[pixel_pin]                
waitx   %[tickC]                     
drvl    %[pixel_pin]                 
waitx   %[tickL]

Reps are linked to a circuit that does the rep. Only one at a time.

The second one should just cancel the first one.

There is no internal stack, or storage for multiple reps.

I see. So the best option in this example would be to replace the first REP with a For loop right?

yes, the outer loop with djnz.

I am overwhelmed with P2 PASM. I still find goodies in P1 PASM, squeezing another 1-4 longs out of something.
