Section 5 Interrupt Controller
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 DTCEA to DTCEF in
the DTC and the DISEL bit of MRB in the DTC.
Table 5.11 Interrupt Source Selection and Clearing Control
Legend:
X : The relevant bit cannot be used.
* : Don’t care
(4) Notes 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.
