External Wait Mask Specification
Specifies whether or nor the external wait input is valid.
The specification by this bit is valid even when the
number of access wait cycles is 0.
0: External wait input is valid.
1: External wait input is ignored.
Reserved
These bits are always read as 0. The write value should
always be 0.
