Section 9 Data Transfer Controller (DTC)
9.2.7
DTCER is a set of registers to specify the DTC activation interrupt source, and comprised of eight
registers; DTCERA to DTCERG, and DTCERI. The correspondence between interrupt sources
and DTCE bits, and vector numbers generated by the interrupt controller are shown in table 9.2.
For DTCE bit setting, use bit manipulation instructions such as BSET and BCLR for reading and
writing. When multiple activation sources are to be set at one time, only at the initial setting,
writing data is enabled after executing a dummy read on the relevant register with all the interrupts
being masked.
Note: n = A to G, and I
