REGISTER 27-1: DEVCFG0: DEVICE CONFIGURATION WORD 0 (CONTINUED)
bit 19-12
PWP<19:12>: Program Flash Write-Protect bits
Prevents selected program Flash memory pages from being modified during code execution.
The PWP bits represent the one’s compliment of the number of write protected program Flash memory
pages.

bit 3
ICESEL: In-Circuit Emulator/Debugger Communication Channel Select bit
1 = In-Circuit Emulator uses EMUC2/EMUD2 pins; In-Circuit Debugger uses
PGC2/PGD2 pins
0 = In-Circuit Emulator uses EMUC1/EMUD1 pins; In-Circuit Debugger uses
PGC1/PGD1 pins
bit 2
Reserved: Write ‘1’
bit 1-0
DEBUG<1:0>: Background Debugger Enable bits (forced to ‘11’ if code-protect is enabled)
11 = Debugger disabled
10 = Debugger enabled
01 = Reserved (same as ‘11’ setting)
00 = Reserved (same as ‘11’ setting)
