5.5
Tables 5.3 lists interrupt exception handling sources, vector addresses, and interrupt priorities.
For default priorities, the lower the vector number, the higher the priority. Modules set at the same
priority will conform to their default priorities. Priorities within a module are fixed.
An interrupt control level can be specified for a module to which an ICR bit is assigned. Interrupt
requests from modules that are set to interrupt control level 1 (priority) by the interrupt control
level and the I and UI bits in CCR are given priority and processed before interrupt requests from
modules that are set to interrupt control level 0 (no priority).
