MK: Interrupt mask flag
PR: Priority specification flag
Interrupt request flag
Flag that controls acknowledgement of maskable interrupt request (1 = Enable, 0 = Disable)
Flag that indicates the priority level of the interrupt currently being serviced (0 = high-priority interrupt
servicing, 1 = No interrupt request acknowledged, or low-priority interrupt servicing)
Interrupt request held pending
