Write Protection Enable: When set, this bit indicates
that the Base and Limit fields in this register are valid and
that writes directed to addresses between them (inclusive)
must be blocked by hardware. The base and limit fields are
ignored when this bit is cleared.
Reserved
Protected Range Limit: This field corresponds to SPI
address bits 23:12 and specifies the upper limit of the
protected range. Address bits 11:0 are assumed to be FFFh
for the limit comparison. Any address greater than the
value programmed in this field is unaffected by this
protected range.
Protected Range Base: This field corresponds to SPI
address bits 23:12 and specifies the lower base of the
protected range. Address bits 11:0 are assumed to be
000h for the base comparison. Any address less than the
value programmed in this field is unaffected by this
protected range.
