10.4
Loopback Mode
Loopback mode will allow internal transmission of
messages from the transmit buffers to the receive
buffers without actually transmitting messages on the
CAN bus. This mode can be used in system
development and testing.
In this mode, the ACK bit is ignored and the device will
allow incoming messages from itself just as if they were
coming from another node. The Loopback mode is a
silent mode, meaning no messages will be transmitted
while in this state (including error flags or acknowledge
signals). The TXCAN pin will be in a recessive state.
The filters and masks can be used to allow only
particular messages to be loaded into the receive
registers. The masks can be set to all zeros to provide
a mode that accepts all messages. The Loopback
mode is activated by setting the mode request bits in
the CANCTRL register.
10.5
Normal Mode
Normal mode is the standard operating mode of the
MCP2515. In this mode, the device actively monitors all
bus messages and generates acknowledge bits, error
frames, etc. This is also the only mode in which the
MCP2515 will transmit messages over the CAN bus.
