ISP connection - non documentated function.

Some device work not fine,
some devices need HiPOwerCLK mode and power from USB,
some device need pull-up resistors and lower clock

since this is not a standardized connection, we cannot guarantee its high-quality operation

Always we reccomend
1) told GND wire
2) D0-CLK-CMD need be same lenght (recomended not over 50-100mm)

mtk devices have no ISP pins. and have bad connect at 90-99% of cases
