3.5
To read a program memory location, the user must write
two bytes of the address to the EEADR and EEADRH
registers, set the EEPGD control bit (EECON1<7>) and
then set control bit RD (EECON1<0>). Once the read
control bit is set, the program memory Flash controller
will use the next two instruction cycles to read the data.
This causes these two instructions immediately follow-

ing the “BSF EECON1,RD” instruction to be ignored.
The data is available in the very next cycle in the
EEDATA and EEDATH registers; therefore, it can be
read as two bytes in the following instructions. EEDATA
and EEDATH registers will hold this value until another
read or until it is written to by the user (during a write
operation).
