After the “BSF EECON1,WR” instruction, the processor
requires two cycles to set up the write operation. The
user must place two NOP instructions after the WR bit is
set. The processor will halt internal operations for the
typical 2 ms, only during the cycle in which the write
takes place (i.e., the last word of the block write). This
is not Sleep mode as the clocks and peripherals will

LWLO = 1, loading the write latches. After the write
cycle, the processor will resume operation with the third
instruction after the EECON1 write instruction.
