WRT<1:0>: Flash Memory Self-Write Protection bits

2 kW Flash memory: PIC16F722/LF722:

= Write protection off

= 000h to 1FFh write-protected, 200h to 7FFh may be modified by EECON control

= 000h to 3FFh write-protected, 400h to 7FFh may be modified by EECON control

= 000h to 7FFh write-protected, no addresses may be modified by EECON control

4 kW Flash memory: PIC16F723/LF723:

= Write protection off

= 000h to 1FFh write-protected, 200h to FFFh may be modified by EECON control

= 000h to 7FFh write-protected, 800h to FFFh may be modified by EECON control

= 000h to FFFh write-protected, no addresses may be modified by EECON control
