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
microcontroller residing on the Emulation Adapter. In principle, pins 3-4, 5-6, 7-8, 9-10, 11-12 and
13-14 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 being connected.
If a different power source is to be used (e.g., in case of a standalone operation), all jumpers
must be removed and power source must be applied to:
·
CVDD_HV_OSC (pin 4),
·
CVDD_HV_ADV (pin 6),
·
CVDD_HV_ADR_S (pin 8),
·
CVDD_HV_IO_MAIN (pin 10),
The EA comes delivered together with the IEA-PS emulation adapter power supply, which simply
plugs into the P2 header row, providing the necessary power supply for Emulation Adapter stan-
dalone operation. Double check that the power supply is configured properly for this particular
Emulation Adapter.
