13.1.4
To read a program memory location, the user must
write two bytes of the address to the EEADRL and
EEADRH registers, set the EEPGD control bit, and
then set control bit RD of the EECON1 register. 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 immedi-
ately following the “BSF EECON1,RD” instruction to be
ignored. The data is available in the very next cycle, in
the EEDATL and EEDATH registers; therefore, it can
be read as two bytes in the following instructions.
EEDATL and EEDATH registers will hold this value until
another read or until it is written to by the user (during
a write operation).

This prevents the user from executing a
two-cycle
instruction after the RD bit is set.
WR bit will be immediately reset to ‘0’ and
no operation will take place.
