P2: Power supply configuration
Emulation Adapter Power supply is configured via the unshrouded 26-pin 2.54 mm header
(P2).

P2 Signal description
Signal Direction is described from the BlueBox perspective.
By default, all jumpers are set to connect your target power supply to the microcontroller resid-
ing on the Emulation Adapter . Only pins 1-2, 3-4, 7-8, 9-10 and 11-12 must be bridged but for
the convenience and ease of use all jumpers are set, except for pins 5-6 and 25-26.
Pin 26 is the polarizer key preventing incorrect connection of the IEA-PS Power converter, when
being plugged in.
If a different power source is used (e.g. a Standalone operation), remove all jumpers and apply
3V3 or 5V to:
·
CVDDA (
pin 2
),
·
CVREFH
(pin 4
, apply the same voltage as on VDDA),
·
CVDDIO_1 (
pin 8
),
·
CVDDIO_2 (
pin 10
),
·
CVDDD (
pin 12
).
Enclosed Power supply package (Power converter and Power adapter) simply plugs into the P2
header row, providing the necessary power supply for Emulation Adapter operation.
LED D1 indicates, if power is supplied to the Emulation Adapter. Refer to the microcontroller doc-
umentation for more details about power voltage designations.
P3 – P6: Emulation device pinout
P3, P4, P5, P6 pinouts match the pinout of the emulation device (176QFP). Refer to the micro-
controller documentation for pin assignment.
J14 and J15: GND connecting points
J14 and J15 provide grounding points on the EA.
