10.1.4
To read a program memory location, the user must
write the Least and Most Significant address bits to the
EEADR and EEADRH registers, set the EEPGD con-
trol bit of the EECON1 register, and then set control bit
RD. Once the read control bit is set, the program mem-
ory Flash controller will use the second instruction
cycle to read the data. This causes the second instruc-
tion immediately following the “BSF
instruction to be ignored. The data is available in the
very next cycle, in the EEDAT and EEDATH registers;
therefore, it can be read as two bytes in the following
instructions.

EEDAT and EEDATH registers will hold this value until
another read or until it is written to by the user.

operation will take place.
