Section 6 Interrupt Controller (INTC)
Figure 6.12 shows the timing for saving to a register bank. Saving to a register bank takes place
between the start of interrupt exception handling and the start of fetching the first instruction in the
interrupt exception service routine.
(2)
The RESBANK (restore from register bank) instruction is used to restore data saved in a register
bank. After restoring data from the register banks with the RESBANK instruction at the end of the
interrupt exception service routine, execute the RTE instruction to return from interrupt exception
service routine.
