7.2.7
DTCER specifies DTC activation interrupt sources. DTCER is comprised of five registers:
DTCERA to DTCERE. The correspondence between interrupt sources and DTCE bits is shown in
tables 7.1 and 7.2. For DTCE bit setting, use bit manipulation instructions such as BSET and
BCLR. Multiple DTC activation sources can be set at one time (only at the initial setting) by
masking all interrupts and writing data after executing a dummy read on the relevant register.
