CHAPTER 22 INTERRUPT FUNCTIONS

22.4.2 Maskable interrupt request acknowledge operation

A maskable interrupt request becomes acknowledgeable when an interrupt request flag is set to 1 and the

interrupt mask (MK) flag is cleared to 0. A vectored interrupt request is acknowledged in an interrupt enable state

(with IE flag set to 1). However, a low-priority interrupt request is not acknowledged during high-priority interrupt

service (with ISP flag reset to 0).

Wait times maskable interrupt request generation to interrupt servicing are shown in Figure 22-3.

Refer to Figures 22-14 and 22-15 for the interrupt request acknowledge timing.

Table 22-3. Times from Maskable Interrupt Request Generation to Interrupt Service

Minimum Time

Maximum Time

Note

When xxPRx = 0

7 clocks

32 clocks

When xxPRx = 1

8 clocks

33 clocks

Note

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

Remark

1 clock: (f

CPU

: CPU clock)

If two or more maskable interrupt requests are generated simultaneously, the request specified for higher priority

with the priority specify flag is acknowledged first. If two or more requests are specified for the same priority with

the priority specify flag, the interrupt request with the higher default priority is acknowledged first.

Any reserved interrupt requests are acknowledged when they become acknowledgeable.

Figure 22-13 shows interrupt request acknowledge algorithms.

When a maskable interrupt request is acknowledged, the contents of program status word (PSW) and program

counter (PC) are saved to stacks, in this order. Then, the IE flag is reset (to 0), and the value of the acknowledged

interrupt priority specify flag is transferred to the ISP flag. Further, the vector table data determined for each interrupt

request is loaded into PC and branched.

Return from the interrupt is possible with the RETI instruction.
