Bits Access
Type
Default Description PowerWell
Upper 4 bits are unused by HW. For address
comparison purposes, lower address bits[9:0]
of incoming address is assumed to be all 1’s.
So, incoming address is checked for less
than or equal to this field.
9:7 RO 3'b0 RSV1 (RSV1)
Reserved
6:0 RW/L 7'b0 MPR Lower Bound (LWR_BOUND)
The Lower Address Bound is compared with
16:10 of the incoming address determine the
lower 1KB aligned value of the Protected
Region.
Upper 4 bits are unused by HW. For address
comparison purposes, lower address bits[9:0]
of incoming address is assumed to be all 0’s.
So, incoming address is checked for greater
than or equal to this field.
