To determine if all the reset/enable have external pull-down or pull-up resistors, we would need to look at the specific pins controlling resets or enables in the schematic design. However, the provided project details do not clearly specify any reset or enable pins or any associated resistors.
Generally, for the MCP25612FD Dual CAN Flexible Data-Rate Transceiver (designator U1), the typical reset pin could be the Standby (STBY) pin. From the provided details, there is no indicated pull-up or pull-down resistors connected to these pins.
However, the absence of such resistors may not necessarily pose a problem if they are not required by the design or logic of this device.
Action items:
  1. Verify whether a pull-up or pull-down resistor is needed for STBY pins on MCP25612FD (designator U1) according to the datasheet and application notes.
  2. If required, identify a suitable value for pull-up or pull-down resistor based on the datasheet's recommendation.
  3. Update the schematic to include revised components (if necessary).
  4. Re-check the circuit and verify the functionality related to reset/enable operation.
Please note that this is an inferred suggestion based on industry practices. Always check datasheets and concrete project info for accurate information. The given details in the project may not be complete so always cross-verify with original sources.

This project is a reference design for a dual CAN (Controller Area Network) Flexible Data-Rate Transceiver based on the MCP25612FD component. The MCP25612FD is designed for high-speed automotive and industrial applications. It includes advanced features such as wake-up capability and high-data rate communication.
MCP25612FD Dual CAN FD Transceiver is a stand-alone Controller Area Network (CAN) Flexible Data Rate (FD) that supports both CAN and CAN FD communication modes. The device provides differential transmit and receive capability at speeds of up to 8 Mbps and includes features such as wake-up from the Standby mode on activity on the CAN bus.
In this project, the MCP25612FD is included with the designator of U1. Other components included in this design are capacitors (C1, C2, C3, C4, C5, C6, C7, C8, C9, C10), resistors (R1, R2, R3, R4), two Diotec Semiconductor diodes (D1 and D2), and a pair of terminals (TERM1, TERM2). All resistors have a resistance of 30Ω, and their manufacturer is not specified. For the capacitors, there are a wide range of capacitances employed, with designators C1, C2, and C3 at 0.1u, 10u, and 0.1u respectively.
The CAN FD Transceiver is set up for two CAN channels (CAN1 & CAN2), each with separate transmit (TX) and receive (RX) lines. The states of these channels are controlled by the Standby nodes (STBY1 & STBY2).
The aim of this design is to allow devices in a CAN network to communicate and thus work together. It is suitable for automotive and industrial applications, where robust and reliable high-speed communication is needed.
