INTERRUPT PRIORITY
The interrupt enable registers are written by the user to enable
individual interrupt sources, whereas the interrupt priority
registers allow the user to select one of two priority levels for
each interrupt. An interrupt of a high priority may interrupt the
service routine of a low priority interrupt, and if two interrupts
of different priority 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, a polling sequence
is observed, as shown in Table 48.

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 49.
