INTERRUPTS (Cont’d)
7.5 INTERRUPT REGISTER DESCRIPTION
CPU CC REGISTER INTERRUPT BITS
Read/Write
Reset Value: 111x 1010 (xAh)
Bit 5, 3 = I1, I0 Software Interrupt Priority
These two bits indicate the current interrupt soft-
ware priority.
These two bits are set/cleared by hardware when
entering in interrupt. The loaded value is given by
the corresponding bits in the interrupt software pri-
ority registers (ISPRx).
They can be also set/cleared by software with the
RIM, SIM, HALT, WFI, IRET and PUSH/POP in-
structions (see “Interrupt Dedicated Instruction
Set” table).
*Note: MCES, TRAP and RESET events can in-
terrupt a level 3 program.
Level 0 (main)
Level 1
Level 2
Level 3 (= interrupt disable*)

INTERRUPT SOFTWARE PRIORITY REGIS-
TERS (ISPRX)
Read/Write (bit 7:4 of ISPR3 are read only)
Reset Value: 1111 1111 (FFh)
These four registers contain the interrupt software
priority of each interrupt vector.
– Each interrupt vector (except RESET and TRAP)
– Each I1_x and I0_x bit value in the ISPRx regis-
– Level 0 can not be written (I1_x=1, I0_x=0). In
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.
*Note: Bits in the ISPRx registers which corre-
spond to the MCES can be read and written but
they are not significant in the interrupt process
management.
Caution: If the I1_x and I0_x bits are modified
while the interrupt x is executed the following be-
haviour 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 previ-
ous one, the interrupt x is re-entered. Otherwise,
the software priority stays unchanged up to the
next interrupt request (after the IRET of the inter-
rupt x).
has corresponding bits in these registers where
its own software priority is stored. This corre-
spondence is shown in the following table.
ters has the same meaning as the I1 and I0 bits
in the CC register.
this case, the previously stored value is kept. (ex-
ample: previous=CFh, write=64h, result=44h)
