Section

   

When an interrupt is generated during execution of the main program, main pro-
gram execution is interrupted immediately and the interrupt program is execut-
ed. The following diagram shows the cyclic operation of the CPM2C when an
interrupt program is executed.

Normally, the results of interrupt program execution are transferred to I/O
memory just after program execution (during I/O refreshing), but IORF(97) can
be used to refresh a specified range of I/O words during execution of the inter-
rupt program. The specified range of I/O words will be refreshed when IORF(97)
is executed.

The normal cycle time is extended by the time required for execution of the inter-
rupt program.

Refer to

Section 7 PC Operations and Processing Time

in the

Programming

Manual

(W353) for more details and precautions on the cycle time.
