interrupt vector addresses
The interrupt vectors and the power-up starting address are located in the address range of 0FFFFh to 0FFE0h.
The vector contains the 16-bit address of the appropriate interrupt handler instruction sequence.

NOTES:
1. Multiple source flags
2. Interrupt flags are located in the module
3. There are eight Port P2 interrupt flags, but only six Port P2 I/O pins (P2.0−5) implemented on the ’C11x1 and ’F11x1A devices.
4. (non)-maskable: the individual interrupt-enable bit can disable an interrupt event, but the general interrupt enable cannot.
Nonmaskable: neither the individual nor the general interrupt-enable bit will disable an interrupt event.
