Table of Contents

If the same interrupt is selected as a DMAC activation source and a DTC activation source or CPU interrupt source,

operations are performed for them independently according to their respective operating statuses and bus mastership

Table 5-11 summarizes interrupt source selection and interrupt source clearance control according to the settings of the

DTA bit of DMABCR in the DMAC, the DTCE bit of DTCERA to DTCERF in the DTC and the DISEL bit of MRB in

Table 5-11 Interrupt Source Selection and Clearing Control

: The relevant interrupt is used. Interrupt source clearing is performed.

(The CPU should clear the source flag in the interrupt handling routine.)

: The relevant interrupt is used. The interrupt source is not cleared.

× : The relevant bit cannot be used.

Note on Use

SCI and A/D converter interrupt sources are cleared when the DMAC or DTC reads or writes to the prescribed register,

and are not dependent upon the DTA bit or DISEL bit.
