Programming KEELOQ device

[Trejep]

I am looking at programming an HCS200 and HCS512 from microchip.com. I have a BP1600 (BPWIN) universal programmer which shows that it supports the devices. My question is that in the datasheets from microchip HCS512 data sheet it shows the hold times, programming waveform etc....but I have no idea how the code or what type of code I should write in order for my programmer to load the correct values into the eeprom. I am used to writing verilog then generating a jedec file to write as well as assembly for generating hex files.....Any help would be greatly appreciated. THANKS!!!
