Relocatable Vector Tables
The 256 bytes beginning with the start address set in the INTB register compose a relocatable vector
table area. Setting an even address in the INTB register results in the interrupt sequence being
executed faster than setting an odd address.

Notes:
1.
Address relative to address in INTB.
2.
Use bits IFSR6 and IFSR7 in the IFSR register to select a source.

3.
In I
C mode, NACK and ACK are interrupt sources.
4.
Use bits IFSR26 and IFSR27 in the IFSR2A register to select a source.
5.
These interrupts cannot be disabled using the I flag.
