REGISTER 28-1: DEVCFG0: DEVICE CONFIGURATION WORD 0 (CONTINUED)

bit 19-10 PWP<9:0>: 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.

Note: These bits are effective only if Boot Flash is also protected by clearing the BWP bit

(DEVCFG0<24>).

bit 9-5 Reserved: Write ‘1’

bit 4-3

ICESEL<1:0>: In-Circuit Emulator/Debugger Communication Channel Select bits

11 = PGEC1/PGED1 pair is used

10 = PGEC2/PGED2 pair is used

01 = PGEC3/PGED3 pair is used

00 = Reserved

bit 2

JTAGEN: JTAG Enable bit(1)

1 = JTAG is enabled

0 = JTAG is disabled

bit 1-0

DEBUG<1:0>: Background Debugger Enable bits (forced to ‘11’ if code-protect is enabled)

1x = Debugger is disabled

0x = Debugger is enabled

Note 1: This bit sets the value for the JTAGEN bit in the CFGCON register.
