19.1
The Enhanced Controller Area Network (ECAN™)
module is a serial interface, useful for communicating
with other CAN modules or microcontroller devices.
This interface/protocol was designed to allow commu-
nications
dsPIC33FJ32GP302/304, dsPIC33FJ64GPX02/X04,
and dsPIC33FJ128GPX02/X04 devices contain up to
two ECAN modules.
The ECAN module is a communication controller imple-
menting the CAN 2.0 A/B protocol, as defined in the
BOSCH CAN specification. The module supports
CAN 1.2, CAN 2.0A, CAN 2.0B Passive and CAN 2.0B
Active versions of the protocol. The module implementa-
tion is a full CAN system. The CAN specification is not
covered within this data sheet. The reader can refer to
the BOSCH CAN specification for further details.
The module features are as follows:
• Implementation of the CAN protocol, CAN 1.2,
• Standard and extended data frames
• 0-8 bytes data length
• Programmable bit rate up to 1 Mbit/sec
• Automatic response to remote transmission
• Up to eight transmit buffers with application speci-
• Up to 32 receive buffers (each buffer can contain
• Up to 16 full (standard/extended identifier)
• Three full acceptance filter masks
• DeviceNet™ addressing support
• Programmable wake-up functionality with

The CAN bus module consists of a protocol engine and
message buffering/control. The CAN protocol engine
handles all functions for receiving and transmitting
messages on the CAN bus. Messages are transmitted
by first loading the appropriate data registers. Status
and errors can be checked by reading the appropriate
registers. Any message detected on the CAN bus is
checked for errors and then matched against filters to
see if it should be received and stored in one of the
receive registers.
19.2
The ECAN module transmits various types of frames
which include data messages, or remote transmission
requests initiated by the user, as other frames that are
automatically generated for control purposes. The
following frame types are supported:
• Standard Data Frame: A standard data frame is
• Extended Data Frame: An extended data frame is
• Remote Frame: It is possible for a destination
• Error Frame: An error frame is generated by any
• Overload Frame: An overload frame can be gen-
