Synopsis
#include <sysreg.h>
void io_space_write(const int address, const unsigned int value)
Description
The
io_space_write
eter to I/O memory space at the address passed as the first parameter.
This function is implemented as a compiler built-in. If the address param-
eter is a constant literal value the compiler will emit a Type 34 instruction
that will be inlined at the point of
addresses, the compiler will call a library compiler support routine to per-
form the required write.

int val = 0xA;
