Write Protection Enable: — R/WL. When set, this bit indicates that the Base and
Limit fields in this register are valid and that writes and erases 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: — R/WL. This field corresponds to FLA address bits 24:12 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.
Read Protection Enable: — R/WL. When set, this bit indicates that the Base and Limit
fields in this register are valid and that read 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 Base: — R/WL. This field corresponds to FLA address bits 24:12 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.
Write Protection Enable: — R/WL. When set, this bit indicates that the Base and
Limit fields in this register are valid and that writes and erases directed to addresses
between them (inclusive) must be blocked by hardware. The base and limit fields are
