8.2.7
DTCER is comprised of seven registers; DTCERA to DTCERG, and DTCERI, and is a register
that specifies DTC activation interrupt sources. The correspondence between interrupt sources and
DTCE bits is shown in table 8.1. For DTCE bit setting, use bit manipulation instructions such as
BSET and BCLR for reading and writing. If all interrupts are masked, multiple activation sources
can be set at one time (only at the initial setting) by writing data after executing a dummy read on
the relevant register.
