The Flash program memory is readable during normal
operation over the full V
data from program memory, five Special Function
Registers (SFRs) are used:
• PMCON1
• PMDATL
• PMDATH
• PMADRL
• PMADRH

PIC16F/LF722A/723A
The value written to the PMADRH:PMADRL register
pair determines which program memory location is
read. The read operation will be initiated by setting the
RD bit of the PMCON1 register. The program memory
Flash controller takes two instructions to complete the
read. As a consequence, after the RD bit has been set,
the next two instructions will be ignored. To avoid
conflict with program execution, it is recommended that
the two instructions following the setting of the RD bit
are NOP. When the read completes, the result is placed
in the PMDATLH:PMDATL register pair. Refer to
Example 18-1 for sample code.
Note:
Code-protect does not effect the CPU
from performing a read operation on the
program memory. For more information,
refer to Section 8.2 “Code Protection”
