есть такая проблемма

при работе с отладчиком программо постоянно вылетает на прерывания

при обращении к процедуре

.def _DSP28x_usDelay

.sect "ramfuncs"

 

.global __DSP28x_usDelay

_DSP28x_usDelay:

SUB ACC,#1

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

LRETR

 

SUB ACC,#1 на этой строчке вылетает в область прерываний и зацикливается

 

interrupt void ILLEGAL_ISR(void) // Illegal operation TRAP

{

EINT;

 

// Insert ISR Code here.......

 

// Next two lines for debug only to halt the processor here

// Remove after inserting ISR Code

asm (" ESTOP0");

for(;;);

} вот в эту процедуру

 

как я понял путает память но немогу понять почему

 

для справки

Можно попробовать вставить твои задержки в мой работающий проект (я проверял его работоспособность на отладочной плате от "Терраэлектроники"). Дальшейший поиск ошибки будет сходен с поиском отличий в двух картинках 8-)
