PIC16F193X/LF193X

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

continue to run. The processor does not stall when

LWLO = 1, loading the write latches. After the write

cycle, the processor will resume operation with the third

instruction after the EECON1 write instruction.
