9.2.2 Relocatable Vector Tables
The 256 bytes beginning with the start address set in the INTB register comprise a reloacatable vector
table area. Table 9.2 lists the relocatable vector tables. Setting an even address in the INTB register
results in the interrupt sequence being executed faster than in the case of odd addresses.

NOTES:
1. Address relative to address in INTB.
2. Use the IFSR6 and IFSR7 bits in the IFSR register to select.
2
3. During I
C bus mode, NACK and ACK interrupts comprise the interrupt source.
4. Use the IFSR26 and IFSR27 bits in the IFSR2A register to select.
5. These interrupts cannot be disabled using the I flag.
6. Bus collision detection:
During IEBus mode, this bus collision detection constitutes the cause of an interrupt.
2
During I
C bus mode, however, a start condition or a stop condition detection constitutes the cause of an interrupt.
