C) Connection of pins 15 and 16 when are configured as logical signal needed for ISP
programming
D) E) When pins 15 and 16 are configured as status of LED OK and LED ERROR
D) before first action with desired ISP device
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.
Specification of ISP connector pins depends on the device, which you want to program. You
can find it in the control SW for programmer (Pg4uw), menu Device / Device Info (Ctrl+F1).
Be aware, the ISP programming way of respective device must be selected. It is indicated by
(ISP) suffix after name of selected device.
