Note 1: The erased (unprogrammed) value of the configuration word is 3FFFh.
2: All of the CP1:CP0 pairs have to be given the same value to enable the code protection scheme listed.
3: Enabling Brown-out Reset automatically enables Power-up Timer (PWRT), regardless of the value of bit
CP0
PWRTEN. Ensure the Power-up Timer is enabled any time Brown-out Reset is enabled.
CP1:CP0: FLASH Program Memory Code Protection bits
11 = Code protection off
