Legend: r = Reserved
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 31-16 Unimplemented: Read as ‘0’
bit 15 LBWPULOCK: Lower Boot Alias Write-protect Unlock bit
1 = LBWPx bits are not locked and can be modified
0 = LBWPx bits are locked and cannot be modified
This bit is only clearable and cannot be set except by any reset.
bit 14-13 Unimplemented: Read as ‘0’
bit 12 LBWP4: Lower Boot Alias Page 4 Write-protect bit
(1)
1 = Write protection for physical address 0x01FC10000 through 0x1FC13FFF enabled
0 = Write protection for physical address 0x01FC10000 through 0x1FC13FFF disabled
bit 11 LBWP3: Lower Boot Alias Page 3 Write-protect bit
(1)
1 = Write protection for physical address 0x01FC0C000 through 0x1FC0FFFF enabled
0 = Write protection for physical address 0x01FC0C000 through 0x1FC0FFFF disabled
bit 10 LBWP2: Lower Boot Alias Page 2 Write-protect bit
(1)
1 = Write protection for physical address 0x01FC08000 through 0x1FC0BFFF enabled
0 = Write protection for physical address 0x01FC08000 through 0x1FC0BFFF disabled
bit 9 LBWP1: Lower Boot Alias Page 1 Write-protect bit
(1)
1 = Write protection for physical address 0x01FC04000 through 0x1FC07FFF enabled
0 = Write protection for physical address 0x01FC04000 through 0x1FC07FFF disabled
bit 8 LBWP0: Lower Boot Alias Page 0 Write-protect bit
(1)
1 = Write protection for physical address 0x01FC00000 through 0x1FC03FFF enabled
0 = Write protection for physical address 0x01FC00000 through 0x1FC03FFF disabled
bit 7 UBWPULOCK: Upper Boot Alias Write-protect Unlock bit
1 = UBWPx bits are not locked and can be modified
0 = UBWPx bits are locked and cannot be modified
This bit is only user-clearable and cannot be set except by any reset.
bit 6 Reserved: This bit is reserved for use by development tools
bit 5 Unimplemented: Read as ‘0’
Note 1: These bits are only available when the NVMKEY unlock sequence is performed and the associated Lock
bit (LBWPULOCK or UBWPULOCK) is set.
Note: The bits in this register are only writable when the NVMKEY unlock sequence is followed.
