Notes:
Some old chips don't carry electronic ID.
In some special cases, several microcontrollers don't provide ID, if copy protection feature in
the chip is set, even if device ID check setting in control program is set to "Enable".

group Target system power supply parameters
This group is available in ISP mode for some types of devices. It contains following settings:
Enable target system power supply - enables supplying of target system from programmer.
Supply voltage for target system is switched on before action with programmed device and is
switched off after action finished. If Keep ISP signals at defined level after operation is
enabled, then programmer will switch off supply voltage after pull-up/pull-down resistors are
deactivated.
Voltage - supply voltage for target system. Supply voltage range is from 2V to 6V.
Note: The voltage value given to target system depends also on current flowing to target
system. To reach exact voltage supply for target system, the proper Voltage and Max. current
values have to be defined. The Max. current value specified has to be as exact as possible
equal to real current consumption of target system.
Max. current - maximum current consumption of powered target system. Current consumption
range is from 0 to 300mA
Voltage rise time - determines skew rate of rising edge of target system power supply
voltage.
Target supply settle time - determines time, after which must be supply voltage in target
system stabilized at set value and target system is ready to any action with programmed
device.
Voltage fall time - determines skew rate of falling edge of target system power supply voltage.
Power down time - determines time after switch off target system power supply within target
system keeps residual supply voltage (e.g. from charged capacitor). After this time elapsed
target system has to be without supply voltage and can be safely disconnected from
programmer.
group Target system parameters
This group is available in ISP mode for some types of devices. It contains following settings:
Oscillator frequency (in Hz) - oscillator's frequency of device (in target system). Control
program sets programming speed by its, therefore is necessary set correct value.
