Each hard trap that occurs must be Acknowledged
before code execution of any type may continue. If a
lower priority hard trap occurs while a higher priority
trap is pending, Acknowledged, or is being processed,
a hard trap conflict occurs.
The device is automatically Reset in a hard trap conflict
condition. The TRAPR status bit (RCON<15>) is set
when the Reset occurs so that the condition may be
detected in software.

Interrupt Sequence
All interrupt event flags are sampled in the beginning of
each instruction cycle by the IFSx registers. A pending
Interrupt Request (IRQ) is indicated by the flag bit
being equal to a ‘1’ in an IFSx register. The IRQ causes
an interrupt to occur if the corresponding bit in the Inter-
rupt Enable (IECx) register is set. For the remainder of
the instruction cycle, the priorities of all pending
interrupt requests are evaluated.
If there is a pending IRQ with a priority level greater
than the current processor priority level in the IPL bits,
the processor is interrupted.
The processor then stacks the current program counter
and the low byte of the processor STATUS register
(SRL), as shown in Figure 8-2. The low byte of the
STATUS register contains the processor priority level at
the time prior to the beginning of the interrupt cycle.
The processor then loads the priority level for this
interrupt into the STATUS register. This action disables
all lower priority interrupts until the completion of the
Interrupt Service Routine.
FIGURE 8-2:
INTERRUPT STACK FRAME
The RETFIE (return from interrupt) instruction unstacks
the program counter and STATUS registers to return
the processor to its state prior to the interrupt
sequence.

Note 1: The user can always lower the priority
level by writing a new value into SR. The
Interrupt Service Routine must clear the
interrupt flag bits in the IFSx register
before lowering the processor interrupt
priority, in order to avoid recursive
interrupts.
2: The IPL3 bit (CORCON<3>) is always
clear when interrupts are being pro-
cessed. It is set only during execution of
traps.
