• Relocatable Vector Tables
The 256 bytes beginning with the start address set in the INTB register comprise a reloacatable vector
table area. Table 1.9.2 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.

Note 1: Address relative to address in INTB.
Note 2: Set the IFSR register's IFSR6 and IFSR7 bits “0”.
Note 3: During I²C mode, NACK and ACK interrupts comprise the interrupt source.
Note 4: Set the IFSR2A register’s IFSR26 and IFSR27 bits “1”.
Note 5: These interrupts cannot be disabled using the I flag.
