10.4.3. Interrupt Priorities
Each interrupt source can be individually programmed to one of two priority levels: low or high. A low priority
interrupt service routine can be preempted by a high priority interrupt. A high priority interrupt cannot be
preempted. Each interrupt has an associated interrupt priority bit in an SFR (IP-EIP2) used to configure its priority
level. Low priority is the default. If two interrupts are recognized simultaneously, the interrupt with the higher
priority is serviced first. If both interrupts have the same priority level, a fixed priority order is used to arbitrate.
10.4.4. Interrupt Latency
Interrupt response time depends on the state of the CPU when the interrupt occurs. Pending interrupts are sampled
and priority decoded each system clock cycle. Therefore, the fastest possible response time is 5 system clock cycles:
1 clock cycle to detect the interrupt and 4 clock cycles to complete the LCALL to the ISR. If an interrupt is pending
when a RETI is executed, a single instruction is executed before an LCALL is made to service the pending interrupt.
Therefore, the maximum response time for an interrupt (when no other interrupt is currently being serviced or the
new interrupt is of greater priority) occurs when the CPU is performing an RETI instruction followed by a DIV as
the next instruction. In this case, the response time is 18 system clock cycles: 1 clock cycle to detect the interrupt, 5
clock cycles to execute the RETI, 8 clock cycles to complete the DIV instruction and 4 clock cycles to execute the
LCALL to the ISR. If the CPU is executing an ISR for an interrupt with equal or higher priority, the new interrupt
will not be serviced until the current ISR completes, including the RETI and following instruction.
