WRT<1:0>: Flash Memory Self-Write Protection bits
2 kW Flash memory: PIC16(L)F720:
11 = Write protection off
10 = 000h to 1FFh write-protected, 200h to 7FFh may be modified by PMCON1 control
01 = 000h to 3FFh write-protected, 400h to 7FFh may be modified by PMCON1 control
00 = 000h to 7FFh write-protected, no addresses may be modified by PMCON1 control
4 kW Flash memory: PIC16(L)F721:
11 = Write protection off
10 = 000h to 1FFh write-protected, 200h to FFFh may be modified by PMCON1 control
01 = 000h to 7FFh write-protected, 800h to FFFh may be modified by PMCON1 control
00 = 000h to FFFh write-protected, no addresses may be modified by PMCON1 control
