You may use the ISSP connection of the miniprog3 to program and debug the PSoC4 directly. No need for any circuitry, just connect.

what the difference between SWD and ISSP circuits?
where can i find and example of ISSP circuit?

The image you posted contains the most simple circuit needed to program a psoc4 using a miniprog3 using the 5pin connector. Just remove all the resistors marked as "No Load" and connect the connector pins to the psoc.

ISSP is for PSOC 1 programming.
This page, the guide, will explain all things Miniprog3 and programming interfaces.

I would like to use the 10 pin header because i already went thorugh the trouble of making a footprint for it in altium. It says in this datasheet (http://www.cypress.com/?docID=44358) I can connect the10 pin header and use it with the 5 pin SWD protocol.
I am having trouble understanding the picture below.
What is Table 3-2 talking about? Are "Signal" pins on the psoc4 or programmer ?

Signal pins on the 5pin and 10 pin conector. If you just want to use SWD jus wire the correspondinf SWD pins from the connector to the psoc4 plus vcc and gnd

Look at the schematics for the CY8C049-42xx prototyping kit. I am currently programming it with a miniprog 3 using the 5-pin header. Even the debugging works. I have to correct the word "ISSP"-interface to "SWD"-interface but they are pin-compatible.

So im guessing for 5 pin SWD programming connection are
MiniProg3 Psoc4
VTARG ---> 3.3v
GND ---> GND
XRES ---> XRES
SCLK ---> SWDCLK
SDAT ---> SWDIO
And for 10 pin connection I think this is what table 3-2 is talking about
MiniProg3 Psoc4
XRES ---> XRES
TDI ---> OPEN
TDO ---> OPEN
TCK ---> SWDCLK
TMS ---> SWDIO
VTARG ---> 3.3v
GND ---> GND

The pins on the minprog are (the right hand pins labeled in white bottom pic) -

Maybe I am getting confused, I think RST, TDI, TDO, TCK,TMS are
concerning JTAG, so its the pins labeled to right you want to use.
VTARG, GND, XRES, SCLK, SDAT.
Maybe you should file a case on this and let forum know what you found out -
To create a technical case at Cypress -
“Support”
“Technical Support”
“Create a Case”
You have to be registered on Cypress web site first.

So are the configurations I put up right?

I called the support line for cypress. This is what they said would be the right configuration.

XRES goes to VDD through a 4.7k resistor, I made it from the PSoC 4 Pioneer board and it has worked fine in my recent designs
