JN516x Mutex, Disable / Enable Interrupts

erkanermis — Fri, 22 Jan 2016 11:51:59 GMT

Hello,

I was using following mutex code in JN5148 in order to disable/enable interrupts. What is the JN516x equivalent of following code?

I am using Eclipse IDE and 802.15.4 stack.

Thanks for your help.

#define ENABLE_INTERRUPTS();\
{\
  register uint32 ru32CtrlReg;\
  asm volatile ("l.mfspr %0, r0, 17;" :"=r"(ru32CtrlReg) : );\
  ru32CtrlReg |= 6;\
    asm volatile ("l.mtspr r0, %0, 17;" : :"r"(ru32CtrlReg));\
}\
#define DISABLE_INTERRUPTS();\
{\
  register uint32 ru32CtrlReg;\
  asm volatile ("l.mfspr %0, r0, 17;" :"=r"(ru32CtrlReg) : );\
  ru32CtrlReg &= 0xfffffff9;\
  asm volatile ("l.mtspr r0, %0, 17;" : :"r"(ru32CtrlReg));\
}\

This is what I use for disabling interrupts:

/// macro (undocumented but found in NXP headers) to disable interrupts

#define MICRO_DISABLE_INTERRUPTS(); \

asm volatile ("b.di;" : : );

#define MICRO_ENABLE_INTERRUPTS(); \

asm volatile ("b.ei;" : : );

Found this in

C:\Jennic\Components\MicroSpecific\Include\MicroSpecific.h

Liam
