18.4  Interrupt Servicing Operations 

 

18.4.1  Maskable interrupt acknowledgment 

A maskable interrupt becomes acknowledgeable when the interrupt request flag is set to 1 and the mask (MK) flag 

corresponding to that interrupt request is cleared to 0.  A vectored interrupt request is acknowledged if interrupts are 

in the interrupt enabled state (when the IE flag is set to 1).  However, a low-priority interrupt request is not 

acknowledged during servicing of a higher priority interrupt request (when the ISP flag is reset to 0).  

The times from generation of a maskable interrupt request until vectored interrupt servicing is performed are listed 

in Table 18-4 below. 

For the interrupt request acknowledgment timing, see 

Figures 18-8

 and 

18-9

.

Note

  If an interrupt request is generated just before a divide instruction, the wait time becomes longer.  

 

Remark

  1 clock: 1/f

 (f

:  CPU clock)  

 

If two or more maskable interrupt requests are generated simultaneously, the request with a higher priority level 

specified in the priority specification flag is acknowledged first.  If two or more interrupts requests have the same 

priority level, the request with the highest default priority is acknowledged first.  

An interrupt request that is held pending is acknowledged when it becomes acknowledgeable.   

Figure 18-7 shows the interrupt request acknowledgment algorithm.   

If a maskable interrupt request is acknowledged, the contents are saved into the stacks in the order of PSW, then 

PC, the IE flag is reset (0), and the contents of the priority specification flag corresponding to the acknowledged 

interrupt are transferred to the ISP flag.  The vector table data determined for each interrupt request is the loaded into 

the PC and branched.   

Restoring from an interrupt is possible by using the RETI instruction.
