relocatable interrupt vector table
The reset, interrupt, and trap vectors are addressed in program space. These vectors are soft — meaning that
the processor, when taking the trap, loads the program counter (PC) with the trap address and executes the
code at the vector location. Four words are reserved at each vector location to accommodate a delayed branch
instruction, either two 1-word instructions or one 2-word instruction, which allows branching to the appropriate
interrupt service routine with minimal overhead.
At device reset, the reset, interrupt, and trap vectors are mapped to address FF80h in program space. However,
these vectors can be remapped to the beginning of any 128-word page in program space after device reset.
This is done by loading the interrupt vector pointer (IPTR) bits in the PMST register with the appropriate
128-word page boundary address. After loading IPTR, any user interrupt or trap vector is mapped to the new
128-word page.
NOTE:
The hardware reset (RS) vector cannot be remapped because a hardware reset loads the
IPTR with 1s. Therefore, the reset vector is always fetched at location FF80h in program space.
