Notes on interrupts
When setting the followings, the interrupt request bit may be set to
“1”.
When switching external interrupt active edge
Related register: Interrupt edge selection register (address 3A
16
)
Timer X mode register (address 27
16
)
Timer Y mode register (address 28
16
)
When switching interrupt sources of an interrupt vector address
where two or more interrupt sources are allocated
Related register: Interrupt source selection bit of A-D control reg-
ister (bit 6 of address 34
16
)
When not requiring for the interrupt occurrence synchronous with
these setting, take the following sequence.
Set the corresponding interrupt enable bit to “0” (disabled).
Set the interrupt edge select bit (polarity switch bit) or the inter-
rupt source selection bit.
Set the corresponding interrupt request bit to “0” after 1 or more
instructions have been executed.
Set the corresponding interrupt enable bit to “1” (enabled).
