dsPIC33FJ64GP804 interrupt vectors

Reset at 0x000000 (a GOTO to the program), then the interrupt vector table from 0x000004: first the 5 traps (non-maskable faults: oscillator failure, address error, stack error, math error…), then the 78 interrupt sources. Each vector is one program word holding its handler's address, so vector n is at 0x000004 + 2n, and IRQ n is vector n + 8. Each source has a flag in IFSx, an enable bit in IECx and a priority from 1 to 7 in IPCx (the Registers page lists them). In XC16 a handler is named after its vector: void __attribute__((interrupt, auto_psv)) _T1Interrupt(void).
