Interrupt Node Enable Registers
Register IEN0 contains the global interrupt masking bit (EA), which can be cleared to block all pending
interrupt requests at once.
The NMI interrupt vector is shared by a number of sources, each of which can be enabled or disabled
individually via register NMICON.
After reset, the enable bits in IEN0, IEN1 and NMICON are cleared to 0. This implies that all interrupt nodes are
disabled by default.
