Interrupts
7.5.2
Caution:
46/193
Interrupt software priority registers (ISPRx)
These four registers contain the interrupt software priority of each interrupt vector.
●
Table 17.
●
●
The reset, and TRAP vectors have no software priorities. When one is serviced, the I1 and
I0 bits of the CC register are both set.
If the I1_x and I0_x bits are modified while the interrupt x is executed the following behavior
has to be considered: If the interrupt x is still pending (new interrupt or flag not cleared) and
the new software priority is higher than the previous one, the interrupt x is re-entered.
Otherwise, the software priority stays unchanged up to the next interrupt request (after the
IRET of the interrupt x).

ISPR3
Each interrupt vector (except reset and TRAP) has corresponding bits in these
registers where its own software priority is stored. This correspondence is shown in the
following
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 cannot be written (I1_x = 1, I0_x = 0). In this case, the previously stored value
is kept (for example, previous value = CFh, write = 64h, result = 44h).
