12.1.5.2
Relocatable Vector Tables
The relocatable vector tables occupy 256 bytes beginning from the starting address set in the INTB register.
Table 12.2 lists the Relocatable Vector Tables.
NOTES:
1. These addresses are relative to those in the INTB register.
2. The I flag does not disable these interrupts.
3. The IICSEL bit in the PMR register switches functions.
