The Password and PAC Registers
Each password set, along with its associated Password Attempt Counters is stored in an 8 byte segment in the
Password section of the Configuration Memory. Figure 30 illustrates password set “z” in the Configuration Memory
map. The Write Password and Write Password PAC are stored in the lower four bytes, while the Read Password and
Read Password PAC are stored in the upper four bytes.
