The bootloader requires that PSEN is held low at reset to enter programming mode. In Flip, the RS setup utility has to be run each time the microcontroller is reset into bootloader mode, before the chip is programmed, or it will give the timeout error.

But press only when the post helped you I got error “Timeout” If yes then how can u programming this IC? CMOS Technology file 1.

The timeout error can mean communication is not established with the microcontroller in bootloader mode. The PSEN pin needs to be grounded at reset to enter bootloader mode.
