Presently I am designing the hardware circuit for my PSoC board.
Based on the schematic of the PSoC development kit CY8CKIT-050 found in the manual for the development kit (p37 under FX2LP programmer), the only connection between the PSoC5 chip and the CY7C68013A-56LTXC is thru the pin15 (XRES) of the PSoC chip to pin20 (PB2/FD2) of CY7C68013A-56LTXC.
Is the programming of the PSoC chip thru the XRES pin (pin15) of the PSoC chip?
I have already found the solution in application note
