Comment to above picture:
picture C) Connection of pins 15 and 16 when are configured as logical signal needed for ISP
programming
pictures D) E) When pins 15 and 16 are configured as status of LED OK and LED ERROR
picture D) before first action with desired ISP device
picture E) after first action with desired ISP device
Notes: When LED OK or LED ERROR ON (shine), this status is presented as logical H, level
of H is 1,8V - 5V depend on H level of desired ISP device.
When LED OK or LED ERROR OFF (not shine), this status is presented as logical L, level of
L is 0V - 0,4V.
The above mentioned values are provided to understand (and also to exactly calculate) the
value of resistors, which isolate (separate) the programmed chip and target system.
