sys_prot_t sys_arch_protect ( void )

sys_prot_t sys_arch_protect(void)
This optional function does a "fast" critical region protection and returns the previous protection level. This function is only called during very short critical regions. An embedded system which supports ISR-based drivers might want to implement this function by disabling interrupts. Task-based systems might want to implement this by using a mutex or disabling tasking. This function should support recursive calls from the same task or interrupt. In other words, sys_arch_protect() could be called while already protected. In that case the return value indicates that it is already protected.
sys_arch_protect() is only required if your port is supporting an operating system.

void sys_arch_unprotect ( sys_prot_t pval )

void sys_arch_unprotect(sys_prot_t pval)
This optional function does a "fast" set of critical region protection to the value specified by pval. See the documentation for sys_arch_protect() for more information. This function is only required if your port is supporting an operating system.
