7.3.1 Reading Program Memory
Program memory is read linearly, similar to how data memory is read. The
MOV instruction is used to read the program memory.
Previously, devices used the table read feature to read the Flash program memory.
However, in dsPIC33A devices, TBLRDL/TBLRDH
features are unimplemented.
Note: The DRBV bit is set
if the data read buffer holds valid data. It is recommended to
invalidate the buffer by writing 0 to the DRBV bit after a
program/erase operation or modification to security access controls
to clear stale data from the buffer.
