5.7
Table 5.5 lists the interrupt response time, which is the time from the occurrence of an interrupt
request until the interrupt exception handling starts and fetching of the first instruction in the
exception service routine begins. The interrupt processing operations differ in the cases when
banking is disabled, when banking is enabled without register bank overflow, and when banking is
enabled with register bank overflow. Figures 5.4 and 5.5 show examples of pipeline operation
when banking is disabled. Figures 5.6 and 5.7 show examples of pipeline operation when banking
is enabled without register bank overflow. Figures 5.8 and 5.9 show examples of pipeline
operation when banking is enabled with register bank overflow.

Remarks
Min. is when the interrupt
wait time is zero.
Max. is when a higher-
priority interrupt request has
occurred during interrupt
exception handling.
Min. is when the interrupt
wait time is zero.
Max. is when an interrupt
request has occurred during
execution of the RESBANK
instruction.
Min. is when the interrupt
