Synopsis
#include <sysreg.h>
void external_memory_write(int, void*, int)
Description
The
external_memory_write
tions to write to external memory at the address passed in the first two
parameters with the value passed in the last parameter. The first parameter
is the value of the top eight bits of the 24-bit external memory address to
write. The second parameter is the lower 16-bits of the address of the
external memory to write.
This function is implemented as a compiler built-in. The emitted instruc-
tions will be inlined at the point of
inclusion of the
