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.

another read or until it is written to by the user.
