TABLE 10-1:
10.2.1
To read a program memory location, the user must:
1.
2.
3.
Once the read control bit is set, the program memory
Flash controller will use the second instruction cycle to
read the data. This causes the second instruction
immediately following the “BSF PMCON1,RD” instruction
to be ignored. The data is available in the very next cycle,
in the PMDATH:PMDATL register pair; therefore, it can
be read as two bytes in the following instructions.
PMDATH:PMDATL register pair will hold this value until
another read or until it is written to by the user.

Clear the CFGS bit of the PMCON1 register.
Then, set control bit RD of the PMCON1 register.

READING THE FLASH PROGRAM
MEMORY
The two instructions following a program
memory read are required to be NOPs.
This prevents the user from executing a
two-cycle
instruction after the RD bit is set.
