My programmer enter to the Program/Verify mode only one times and I can't en
ter to this mode again until VDD is turn off.
I use following routines:
Holding pins GP1, GP0 and MCLR low; turning off VDD and then restoring VDD a
gain, next instruction raise MCLR to 13V.
This is not enters microcontroller to the Program/Verify Mode.
