HiDoes anyone know of either (a) some Freescale example code for setup of the PLL, or (b) a solid rationale for the NOPs in the following. I have to justify (or otherwise) the presence of the NOPs in some code written by a guy who left the company.Code:
PLL_ON; // macro to turn on PLL
#asm
"nop";
"nop";
"nop";
"nop";
#endasm
while((CRGFLG & 0x08) == 0){} // poll for LOCK
The logic behind this question is simple, if they should be there, then some justification should be made, if not they should be removed. Unfortunately the old saying "if it aint broke dont fix it" doesn't hold in this case
