To ensure proper reading of data from tables in

;Disable the interrupts
;This NOP is required for the workaround.
;This initiates program memory read.
;Any instructions here are ignored while program memory is read in the
;second instruction cycle after BSF EECON1, RD.
;These four NOP's are required for the workaround.
;Enable the interrupts

in
Work around
A software workaround will enable Flash program
memory to function as published. One NOP should
precede and six NOPs should follow the instruction
that sets the read bit.
Replace the required 3-instruction sequence,
shown in Example 3-3 of the Data Sheet, with the
sequence shown in Example 1 (below). The
interrupts should be disabled during this process.
This problem is specific to Rev. B0 and has been
resolved by Rev. B2 of the silicon (date codes later
than 0242xxx).
