WRPROT0
Write protection for Flash 0 − 32 bits. Each bit corresponds to a 4 kB flash
section. Writing 0 to a bit protects the corresponding section of flash. This
register is read-only if the write protection in flash has been programmed.
0xFFFFFFFF RW

This register is key protected; therefore, the key (0xF123F456) must be entered in FEEKEY. After writing to FEECON1, a value other than
0xF123F456 must be written again to FEEKEY to reassert the key protection.

DBG
JTAG debug enable. If this bit is 1, access via the serial wire debug interface
is enabled. If this bit is 0, access via the serial wire debug interface is
disabled. The kernel set this bit to 1 when it has finished executing, thus
enabling debug access to a user.
0x1
RW
0: disable JTAG access.
1: enable JTAG access.
