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
PIC24HJXXXGPX06A/X08A/X10A devices contain up
to two ECAN modules.
The CAN module is a communication controller imple-
menting the CAN 2.0 A/B protocol, as defined in the
BOSCH specification. The module will support CAN 1.2,
CAN 2.0A, CAN 2.0B Passive and CAN 2.0B Active
versions of the protocol. The module implementation is
a full CAN system. The CAN specification is not covered
within this data sheet. The reader may 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 8 transmit buffers with application specified
• Up to 32 receive buffers (each buffer may contain
• Up to 16 full (standard/extended identifier)
• 3 full acceptance filter masks
• DeviceNet™ addressing support
• Programmable wake-up functionality with
• Programmable Loopback mode supports self-test

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 CAN module transmits various types of frames
which include data messages, remote transmission
requests and as other frames that are automatically
generated for control purposes. The following frame
types are supported:
• Standard Data Frame:
• Extended Data Frame:
• Remote Frame:
• Error Frame:
• Overload Frame:
• Interframe Space:
receiver and transmitter error states
for both CAN1 and CAN2) for time-stamping and
network synchronization
A standard data frame is generated by a node when
the node wishes to transmit data. It includes an 11-bit
standard identifier (SID) but not an 18-bit extended
identifier (EID).
An extended data frame is similar to a standard data
frame but includes an extended identifier as well.
It is possible for a destination node to request the
data from the source. For this purpose, the
destination node sends a remote frame with an iden-
tifier that matches the identifier of the required data
frame. The appropriate data source node will then
send a data frame as a response to this remote
request.
An error frame is generated by any node that detects
a bus error. An error frame consists of two fields: an
error flag field and an error delimiter field.
An overload frame can be generated by a node as a
result of two conditions. First, the node detects a
dominant bit during interframe space which is an ille-
gal condition. Second, due to internal conditions, the
node is not yet able to start reception of the next
message. A node may generate a maximum of 2
sequential overload frames to delay the start of the
next message.
Interframe space separates a proceeding frame (of
whatever type) from a following data or remote
frame.
