8.9.10
When a conflict occurs between the generation of the NMI interrupt and the DTC activation, the
NMI interrupt has priority. Thus the ERR bit is set to 1 and the DTC is not activated.
It takes 1 × Bcyc + 3 × Pcyc for determining DTC stop by NMI, 2 × Bcyc for determining DTC
activation by IRQ, and 1 × Pcyc for determining DTC activation by peripheral modules.
8.9.11
Once the DTC has accepted an activation request, the DTC does not accept the next activation
request until the sequence of DTC processing that ends with writeback has been completed.
