bit 0
Legend:
R = Readable bit
-n = Value at POR
C = Clearable Only bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown
bit 7-4
bit 3-1
bit 0
Unimplemented: Read as ‘0’
BSS<2:0>: Boot Segment Program Flash Code Protection bits(1)
111 = No boot segment; all program memory space is General Segment
110 = Standard security boot segment starts at 0200h, ends at 0AFEh
101 = Standard security boot segment starts at 0200h, ends at 15FEh(2)
100 = Reserved
011 = Reserved
010 = High-security boot segment starts at 0200h, ends at 0AFEh
001 = High-security boot segment starts at 0200h, ends at 15FEh(2)
000 = Reserved
BWRP: Boot Segment Program Flash Write Protection bit(1)
1 = Boot segment may be written
0 = Boot segment is write-protected
Note 1: Code protection bits can only be programmed by clearing them. They can be reset to their default factory
state (‘1’), but only by performing a bulk erase and reprogramming the entire device.
2: This selection is available only on PIC24F16KL40X devices.
