InDart used the following pins, ( ST7LITE09 )

If I want to use these pins, is it I cannot use InDart ICP ?

Or I need to program the flash first

PA5: ICC DATA

PA6: ICC CLK

PB4: ICC OSC_CLK

You can use these pins in youe applcation if you only need to program the device, if you want to use the indart for in-circuit debugging then these pins have to be left at reset state and not modified by your application.

Hope this helps

These pins are used when you are programming using ICC mode.

PB4: ICC OSC_CLK pin may or may not be used depending upon the option byte(ICP OPT disable/enable). After programming, you can use these pins as normal port pins unless you are not using these pins for in circuit debugging.
