Chapter 3 Interrupts

■Maskable Interrupt

Figure 3-1-6 shows the processing flow when a second interrupt with a lower priority level (xxxLV1- xxxLV0='10') arrives during the processing of one with a higher priority level (xxxLV1-xxxLV0='00').

(xxxLV1,0='11')

Parentheses ( ) indicate hardware processing.

*1 If during the processing of the first interrupt, an interrupt request with an interrupt level (IL) numerically lower than the interrupt mask (IM) arrives, it is accepted as a nested interrupt. If IL ≥ IM, however, the interrupt is not accepted.

*2 The second interrupt, postponed because its interrupt level (IL) was numerically greater than the interrupt mask (IM) for the first interrupt service routine, is accepted when the first interrupt handler returns.
