Priority Level Structure
All interrupt sources are combined in priority level
groups and controlled in terms of priority level by bits in
the ip0 and ip1 registers.

Serial channel 0 interrupt
Each group of interrupt sources can be programmed
individually to one of four priority levels by setting or
clearing one bit in the special function register ip0 and
one in ip1. If requests of the same priority level are
received simultaneously, an internal polling sequence
determines which request is serviced first.
For example, in Table 38 the two interrupts, Timer 0
interrupt and external pin int2, are combined in a
priority group and are priority level controlled by the
combination of bit0 from the ip0 register and bit0 from
int5
