why can't support stc89c52

[stan12138]

stcflash is a great project, thank you for your work! But when I try to use it dowmload program for stc89c52 mcu, it doesn't work, blocking at "Detecting target...". I want know why stcflash doesn't support stc89c52, Is it possible to support stc89c52? And my second question is how do you find the protocols for these mcu?

But my stc89c52rc can be supported and successfully downloaded. I found this, not knowing if it's detailed and comprehensive enough.
