INTERRUPT PRIORITY
The interrupt enable registers are written by the user to enable
individual interrupt sources; the interrupt priority registers
allow the user to select one of two priority levels for each
interrupt. A high priority interrupt can interrupt the service
routine of a low priority interrupt, and if two interrupts of
different priorities occur at the same time, the higher level
interrupt is serviced first. An interrupt cannot be interrupted by
another interrupt of the same priority level. If two interrupts of
the same priority level occur simultaneously, the polling sequence,
as shown in Table 61, is observed.

INTERRUPT VECTORS
When an interrupt occurs, the program counter is pushed onto
the stack, and the corresponding interrupt vector address is
loaded into the program counter. The interrupt vector addresses
are shown in Table 62.
