To keep things a bit compact, the DSL stereotypes «pin» and «node» are not shown here, but their icons are:

MagicDraw/Cameo: Display option: You can choose whether to show Domain Specific Language (DSL) stereotypes: 'None', 'All', 'Only Last'

Also, the multiplicities are not shown on the Ports or net nodes (and are assumed to be 1).

A board reset can be performed via the reset button, via a pin on :Header3, or via ICSP.

The SPI connections (MOSI/MISO/SCK) between one ICSP header and the main mcu ATmega2560 chip are not directly relevant to the reset, there's just shown anyway.

A board reset ultimately also affects the ATmega16U2 chip via DTR/HWR to its p13.

Notes
[DISPLAY, POLICY, SETTINGS, STYLE, TOOL]{STRONG} Webel: SysML symbol colour styles: Recommend use black symbol borders and no symbol fill (or white symbol fill) EXCEPT for special highlighting. Recommend DO NOT use the default VENDOR-SPECIFIC line and fill colours for symbols! [TIP IS MOSTLY IGNORED]
[DISPLAY, POLICY, SETTINGS, STYLE, TOOL]{STRICT} SysML: MagicDraw/Cameo: Diagram Style: Recommend DO NOT use shadows or gradient fill adornments on diagrams! [TIP OFTEN IGNORED]
[ISSUE, TOOL] MagicDraw UML/SysML/Cameo 19SP3: Sometimes on application of a named Association as the Type of a Connector that already has an InformationFlow (or ItemFlow) applied, the direction of the InformationFlow (or ItemFlow) indicator swaps.
[DISPLAY, MODELLING, OPTION, TIP, TOOL]{INFORMATIVE} MagicDraw/Cameo: Display option: You can choose whether to show Domain Specific Language (DSL) stereotypes: 'None', 'All', 'Only Last'
[DISPLAY, MODELLING, POLICY, TIP, TOOL]{INFORMATIVE} MagicDraw/Cameo: Rule: Internal Block Diagram and Block structure compartment: only one symbol for a given Property may be shown.
