MCP2515

9.0

RESET

The MCP2515 differentiates between two Resets:

Hardware Reset – Low on RESET pin

SPI Reset – Reset via SPI command

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 VDD reaches

operating voltage, as indicated in the electrical

specification (tRL).

R1(2)

VDD

D(1)

Note 1: The diode D helps discharge the capacitor quickly when VDD powers down.

2: R1 = 1 k

 to 10 k will limit any current flowing into RESET from external

capacitor C, in the event of RESET pin breakdown due to Electrostatic

Discharge (ESD) or Electrical Overstress (EOS).
