15. Delayed Interrupt Generation Module
The delayed interrupt generation module is used to generate the task switching interrupt. Interrupt requests to
the F2MC-16L CPU can be generated and cleared by software using this module.
(1) Register Details
The DIRR register controls generation and clearing of delayed interrupt requests. Writing “1” to the register
generates a delayed interrupt request. Writing “0” to the register clears the delayed interrupt request. The register
is set to the interrupt cleared state by a reset. Either “0” or “1” can be written to the reserved bits. However,
considering possible future extensions, it is recommended that the set bit and clear bit instructions are used for
register access.
