Interrupt software priority registers (ISPRX)
These four registers contain the interrupt software priority of each interrupt vector.
The reset, TRAP and MCES vectors have no software priorities. When one is serviced, the
I1 and I0 bits of the CC register are both set.

Each interrupt vector (except reset and TRAP) has corresponding bits in those
registers where its own software priority is stored. This correspondence is shown in
Table
Each I1_x and I0_x bit value in the ISPRx registers has the same meaning as the I1
and I0 bits in the CC register.
Level 0 can not be written (I1_x = 1, I0_x = 0). In this case, the previously stored value
is kept. (example: previous = CFh, write = 64h, result = 44h)
