The MCP2515 differentiates between two resets:
1.
2.
Both of these resets are functionally equivalent. It is
important to provide one of these two resets after
power-up to ensure that the logic and registers are in
their default state. A hardware reset can be achieved
automatically by placing an RC on the RESET pin. (see
Figure 9-1). The values must be such that the device is
held in reset for a minimum of 2 µs after V
operating voltage, as indicated in the electrical
specification (t
