Operation
Configuration
DIP1: Target reset configuration
DIP switch DIP1 connects the Emulation Adapter reset line and the target reset line and is on (position next to the white dot) by default. The Emulation Adapter also features a Reset push button (SW1).
If having problems establishing the initial debug session with the Emulation Adapter, adjust the DIP switch DIP1 to the off position (position away from the white dot) and try again.
DIP2: Clock source configuration
DIP switch DIP2 selects a clock source for the emulation device.
When the switch is in position next to the white dot (default setting), it selects the crystal circuit oscillator from the target.
When the crystal circuit of the emulation adapter is to be used instead of the target board's crystal circuit, adjust the switch in the position away from the white dot. In this case, the Q1 socket on the Emulation Adapter must also be populated with an adequate crystal.
|
The Emulation Adapter may not operate when your target board’s crystal circuit is used as the clock source. A typical design guideline is that the crystal should be as close as possible to the microcontroller. The crystal on your target board might not oscillate in conjunction with the Emulation Adapter when the clock lines (XTAL, EXTAL) between the crystal and the emulation device on the Emulation Adapter become too long, thus affecting the impedance of the crystal circuit. |
|
Separately packed 16 MHz crystal can be used as a 16 MHz external clock (XOSC) source to the emulation device. If a different clock frequency is required, insert an adequate crystal into the Q1 socket and replace C1 (default 22pF populated) and C2 (default 22pF populated) accordingly. Crystal socket Q1 is by default not populated (NP). |

Trace port
The superset microcontroller device being used on the Emulation Adapter features Slow and Fast trace signals. Slow trace signals are connected to ARM Mictor 38 and ARM CoreSight 20 target connectors provided by the Emulation Adapter. Fast trace signals share microcontroller I/O ports with other peripheral functionalities, and for this reason, they are connected towards the target for the user to use them according to their target application configuration and usage.

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 on the Emulation Adapter. Note that only pins 1-2, 3-4 and 5-6 of the P2 connector must be bridged with jumpers, but for the convenience and ease of use, all jumpers are set. Pin 26 is the Key pin preventing incorrect connection of the IEA-PS Power converter when being used and plugged in.
If, for some reason, a power supply is not provided from the target side (e.g., a standalone operation), all jumpers must be removed and, depending on the application, 3V3 or 5V must be applied to the following pins:
•P2 pin 2 - VDD_HV_A
•P2 pin 4 - VDD_HV_B
•P2 pin 6 - VREFH
An enclosed Power supply package (Power converter and Power adapter) provides these voltages by simply plugging in the Power converter to the P2 header row.
LED D1 indicates if the Emulation Adapter is powered.
Refer to the microcontroller documentation for more details on VDD_HV_A, VDD_HV_B and VREFH signals.
J28: VREFH limiting circuit
The Emulation adapter holds a limiting circuit to prevent VREFH exceeding VDD_HV_A. By default, the limiting circuit is enabled by J28 in position 2-3 (default). In case the user would like to bypass the limiting circuit, the J28 jumper should be set to 1-2.
J30: 1V5 power
1V5 can be generated on the Emulation Adapter or provided from the target board. By default, 1V5 is generated on the Emulation Adapter by J30 in the position 2-3 (default). In case the user would like to provide it from the target board, the J30 jumper should be set to 1-2.
J31: VDD_HV_B power
In case the target device does not provide VDD_HV_B, voltage to the mentioned rail should be provided via VDD_HV_A. This can be achieved by enabling J31. By default, J31 is disabled. In standalone mode, J31 should be disabled.
J4 and J5: GND connection points
In case a good ground connection is required, connection points bridge J4 and pin J5 provide easy access to the Emulation Adapter's GND potential.

P3–P6: Emulation device pinout
Connectors P3, P4, P5 and P6 on the bottom side of the Emulation Adapter expose all emulation device signals toward the Conversion board, through which the Emulation Adapter adapts to different pin count packages.
Standalone operation
The Emulation Adapter is delivered with all the components required for a Standalone operation.
Power supply
Use the enclosed IEA-PS Emulation Adapter Power converter and adapter.
A Power supply package, which is delivered with the Emulation Adapter, is required when:
•The Emulation Adapter is used as a standalone device .
•The target board doesn’t provide an accurate supply voltage.
•The target board doesn’t provide sufficient current for the Emulation Adapter operation.
The Power converter can supply either 3.3 V or 5 V. The array of jumpers J0–J9 selects 3.3 V or 5 V voltage on the P3 connector, which connects to the Emulation Adapter.

P3 connector and J0–J9 jumper correlation table
For example, when J2 is in the 3V3 position, it supplies 3.3 V to pin 6 of the P3 connector. When J2 is in the 5V position, it supplies 5 V to pin 6 of the P3 connector pin.
|
Be careful not to supply 5 V to the microcontroller power supply pin, which has declared a maximum voltage 3.3 V! Refer to the microcontroller documentation for detailed information on power supply. |
