Program Example of Delayed Interrupt Generation Module
This section gives a program example of the delayed interrupt generation module.
■
Program Example of Delayed Interrupt Generation Module
●
Processing specification
The main program writes "1" to the R0 bit in the delayed interrupt request generate/cancel register (DIRR)
to generate a delayed interrupt request and performs task switching.
