When overwriting of the DTC-transfer enable register (DTCER) and the generation of an interrupt
that is a source for DTC activation are in competition, activation of the DTC and interrupt
exception processing by the CPU will both proceed at the same time. Depending on the conditions
at this time, doubling of interrupts may occur. If there is a possibility of competition between
overwriting of DTCER and generation of an interrupt that is a source for DTC activation, proceed
with overwriting of DTCER according to the relevant procedure given below.
