Relocatable Vector Tables
The relocatable vector tables occupy 256 bytes beginning from the starting address set in the INTB register.
Notes:
1. These addresses are relative to those in the INTB register.
2. Selectable by the IICSEL bit in the SSUIICSR register.
3. These interrupts are not disabled by the I flag.
4. Voltage monitor 1/comparator A1 interrupt is selected when the IRQ1SEL bit in the CMPA register is set to 1
(maskable interrupt).
5. Voltage monitor 2/comparator A2 interrupt is selected when the IRQ2SEL bit in the CMPA register is set to 1
(maskable interrupt).
