WebJul 17, 2024 · Bit 0 of the special register FAULTMASK is the fault mask bit. If this bit is 1, all interrupts and faults are not allowed. If the bit is 0, then interrupts and faults are allowed. The nonmaskable interrupt (NMI) is not affected by these mask bits. Base Priority Mask Register. The BASEPRI register defines the priority of the executing software ... WebThe ‘interrupt priority mask’ register (ICCPMR) allows interrupt ID’s above the specified value to be disabled. Only the 8 lowest bits in this register are meaningful. Since we are configuring a single interrupt we can leave all other interrupts unmasked. The below code unmasks all interrupt priorities (255 and below are enabled)
