6.4
6.4.1
To configure an interrupt source at initialization:
1.
2.
3.
4.
6.4.2
The method used to declare an ISR and initialize the
IVT with the correct vector address depends on the
programming language (C or assembler) and the lan-
guage development tool suite used to develop the
application.
In general, the user application must clear the interrupt
flag in the appropriate IFSx register for the source of
interrupt that the ISR handles. Otherwise, program will
re-enter the ISR immediately after exiting the routine. If
the ISR is coded in assembly language, it must be ter-
minated using a RETFIE instruction to unstack the
saved PC value, SRL value and old CPU priority level.

Note:
Set the NSTDIS bit (INTCON1<15>) if nested
interrupts are not desired.
Select the user-assigned priority level for the
interrupt source by writing the control bits in the
appropriate IPCx register. The priority level will
depend on the specific application and type of
interrupt source. If multiple priority levels are not
desired, the IPCx register control bits for all
enabled interrupt sources can be programmed
to the same non-zero value.
Clear the interrupt flag status bit associated with
the peripheral in the associated IFSx register.
Enable the interrupt source by setting the inter-
rupt enable control bit associated with the
source in the appropriate IECx register.
Interrupt Setup Procedures
INITIALIZATION
INTERRUPT SERVICE ROUTINE
At a device Reset, the IPCx registers are
initialized such that all user interrupt
sources are assigned to priority level 4.
Preliminary
6.4.3
A Trap Service Routine (TSR) is coded like an ISR,
except that the appropriate trap status flag in the
INTCON1 register must be cleared to avoid re-entry
into the TSR.
6.4.4
All user interrupts can be disabled using this
procedure:
1.
2.
To enable user interrupts, the POP instruction can be
used to restore the previous SR value.
The DISI instruction provides a convenient way to dis-
able interrupts of priority levels 1-6 for a fixed period of
time. Level 7 interrupt sources are not disabled by the
DISI instruction.
Note:
Push the current SR value onto the software
stack using the PUSH instruction.
Force the CPU to priority level 7 by inclusive
ORing the value OEh with SRL.
TRAP SERVICE ROUTINE
INTERRUPT DISABLE
Only user interrupts with a priority level of
7 or lower can be disabled. Trap sources
(level 8-level 15) cannot be disabled.
