Syntax
void __pld(...)
Where:
... denotes any number of pointer or integer arguments specifying addresses
of memory to prefetch.
Restrictions
If the target architecture does not support data prefetching, this intrinsic has no effect.
Example
extern int data1;
extern int data2;
volatile int* interrupt = (volatile int *)0x8000;
volatile int* uart = (volatile int *)0x9000;
void get(void)
{
__pld(data1, data2);
while (!*interrupt);
*uart = data1; // trigger uart as soon as interrupt occurs
*(uart+1) = data2;
}

4.7.20 __pldw
This intrinsic inserts a PLDW instruction into the instruction stream generated by the
compiler. It enables you to signal to the memory system from your C or C++ program
that a data load from an address with an intention to write is likely in the near future.
Syntax
void __pldw(...)
Where:
... denotes any number of pointer or integer arguments specifying addresses
of memory to prefetch.
