Yes, SFDP (0x5A)

I can't send sfdp data block because I can't get it from my Puya chips.
The datasheets for Puya chips can be found at it's original site https://www.puyasemi.com/h_xilie715.html
but at now there is an error to access to any pdf files on this site. The saved datasheets can be
downloaded from sellers, for example https://datasheet.lcsc.com/lcsc/2304140030_PUYA--P25Q16H-SUH-IR_C559219.pdf
