9.2.2 Autovector Register (AVR)
The autovector register (AVR), shown in Figure 9-3, enables external interrupt sources to
be autovectored, using the vector offset defined in Table 2-19 in Section 2.8, “Exception
Processing Overview.” Note that the autovector enable for internal interrupt sources applies
for respective ICRs.
Table 9-5 describes AVR fields.
