Note:

A 1 can be written only once. Once 1 is written to the DNMIE bit, subsequent write accesses are disabled.
DPSIER is used to enable or disable the external interrupt pin that cancels deep software standby mode.
DPSIER is initialized by the reset signal from the RES# pin, but is not initialized by the internal reset signal that cancels
deep software standby mode.
Note that modifying the DPSIER register setting causes a change in the internal state of control over the input buffer of
the corresponding pin. At that time, an edge might be generated internally according to the pin state, and if this happens,
it leads to setting of the DPSIFR register value to 1. Before causing a shift to deep software standby mode, set the
DPSIFR register value to 0.
Also note that the input buffer is disabled on a transition to deep software standby mode if the value of the DPSIER
register is 0. At that time, an edge might be generated internally according to the pin state, and if this happens, it leads to
setting of the DPSIFR register value to 1. In this case, however, if the DPSIEGR register value is 0, no rising edges are
detected and thus the DPSIFR register value will not be 1.
