Refer to the microcontroller user's manual for more details which power supply designation in
the above table belongs to which power supply.
By default all jumpers are set and connect target power supply coming from the target to the mi-
crocontroller residing on the emulation adapter. In principle, pins 3-4, 5-6, 7-8, must be bridged
only but for the convenience and ease of use, all jumpers are set except for pins 25-26. Pin 26 is
the polarizer key preventing incorrect connection of the IEA-PS power supply, when connected.
