17.3
The CAN module can operate in one of several operation
modes selected by the user. These modes include:
• Initialization mode
• Disable mode
• Normal Operation mode
• Listen Only mode
• Loopback mode
• Error Recognition mode
Modes are requested by setting the REQOP<2:0> bits
(CiCTRL<10:8>). Entry into a mode is Acknowledged
by monitoring the OPMODE<2:0> bits (CiCTRL<7:5>).
The module does not change the mode and the
OPMODE bits until a change in mode is acceptable,
generally during bus Idle time which is defined as at
least 11 consecutive recessive bits.
17.3.1
In the Initialization mode, the module does not transmit
or receive. The error counters are cleared and the inter-
rupt flags remain unchanged. The programmer has
access to Configuration registers that are access
restricted in other modes. The module protects the user
from accidentally violating the CAN protocol through
programming errors. All registers that control the con-
figuration of the module can not be modified while the
module is on-line. The CAN module is not allowed to
enter the Configuration mode while a transmission is
taking place. The Configuration mode serves as a lock
to protect the following registers.
• All Module Control registers
• Baud Rate and Interrupt Configuration registers
• Bus Timing registers
• Identifier Acceptance Filter registers
• Identifier Acceptance Mask registers
17.3.2
In Disable mode, the module does not transmit or
receive. The module has the ability to set the WAKIF bit
due to bus activity, however, any pending interrupts
remain and the error counters retain their value.
If the REQOP<2:0> bits (CiCTRL<10:8>) = 001, the
module enters the Module Disable mode. If the module is
active, the module waits for 11 recessive bits on the CAN
bus, detects that condition as an Idle bus, and then
accepts the module disable command. When the
OPMODE<2:0>
indicates whether the module successfully went into
Module Disable mode. The I/O pins revert to normal I/O
function when the module is in the Module Disable mode.

(CiCTRL<7:5>) = 001,

The module can be programmed to apply a low-pass
filter function to the CiRX input line while the module or
the CPU is in Sleep mode. The WAKFIL bit
(CiCFG2<14>) enables or disables the filter.
17.3.3
Normal
REQOP<2:0> = 000. In this mode, the module is acti-
vated and the I/O pins assume the CAN bus functions.
The module transmits and receives CAN bus
messages via the CxTX and CxRX pins.
17.3.4
If the Listen Only mode is activated, the module on the
CAN bus is passive. The transmitter buffers revert to
the port I/O function. The receive pins remain inputs.
For the receiver, no error flags or Acknowledge signals
are sent. The error counters are deactivated in this
state. The Listen Only mode can be used for detecting
the baud rate on the CAN bus. To use this, it is neces-
sary that there are at least two further nodes that
communicate with each other.
17.3.5
The module can be set to ignore all errors and receive
any message. The Listen All Messages mode is acti-
vated by setting the REQOP<2:0> bits to ‘111’. In this
mode, the data which is in the message assembly buf-
fer until the time an error occurred, is copied in the
receive buffer and can be read via the CPU interface.
17.3.6
If the Loopback mode is activated, the module
connects the internal transmit signal to the internal
receive signal at the module boundary. The transmit
and receive pins revert to their port I/O function.

Operating
Typically, if the CAN module is allowed to
transmit in a particular mode of operation
and a transmission is requested immedi-
ately after the CAN module has been
placed in that mode of operation, the mod-
ule waits for 11 consecutive recessive bits
on the bus before starting transmission. If
the user switches to Disable mode within
this 11-bit period, then this transmission is
aborted and the corresponding TXABT bit
is set and TXREQ bit is cleared.
