7.2 Interrupts
The PIC32MZ EF family uses variable offsets for vector spacing. This allows
the interrupt vector spacing to be configured according to application needs. A
unique interrupt vector offset can be set for each vector using its associated
OFFx register.
For details on the Variable Offset feature, refer to 8.5.2 “Variable Offset” in
Section 8. “Interrupt Controller” (DS60001108) of the “PIC32 Family
Reference Manual”.
Table 7-2 provides the Interrupt IRQ, vector and bit location information.
