21.3
The ECAN 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
• Listen All Messages mode
• Loopback mode
Modes are requested by setting the REQOP<2:0> bits
(CiCTRL1<10:8>). Entry into a mode is Acknowledged
by
(CiCTRL1<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.
21.3.1
In the Initialization mode, the module does not transmit
or receive. The error counters are cleared and the inter-
rupt flags remain unchanged. The user application 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 which control the
configuration of the module can not be modified while
the module is on-line. The ECAN 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
21.3.2
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
remains and the error counters retains their value.
If the REQOP<2:0> bits (CiCTRL1<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, detect that condition as an Idle bus, then accept the
module disable command. When the OPMODE<2:0>
bits (CiCTRL1<7:5>) = 001, that indicates whether the
module successfully went into Module Disable mode.
The I/O pins reverts to normal I/O function when the
module is in the Module Disable mode.

bits
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.
21.3.3
Normal
REQOP<2:0> = 000. In this mode, the module is
activated and the I/O pins assumes the CAN bus
functions. The module transmits and receive CAN bus
messages via the CiTX and CiRX pins.
21.3.4
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.
21.3.5
The module can be set to ignore all errors and receive
any message. The Listen All Messages mode is acti-
vated by setting REQOP<2:0> = ‘111’. In this mode,
the data which is in the message assembly buffer, until
the time an error occurred, is copied in the receive buf-
fer and can be read via the CPU interface.
21.3.6
If the Loopback mode is activated, the module con-
nects 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.
Note:
Operation
Typically, if the ECAN module is allowed to
transmit in a particular mode of operation
and a transmission is requested immedi-
ately after the ECAN 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.
