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
REGISTER 26-1: DEVCFG0: DEVICE CONFIGURATION WORD 0 (CONTINUED)
Note 1: This bit sets the value for the JTAGEN bit in the CFGCON register.
2: The PGEC4/PGED4 pin pair is not available on all devices. Refer to the “Pin Diagrams” section for
availability.
3: The PWP<8:7> bits are only available on devices with 256 KB Flash.
