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 communications within
noisy
PIC24HJ64GPX02/X04 and PIC24HJ128GPX02/X04
devices contain up to two ECAN modules.
The ECAN module is a communication controller
implementing 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

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

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:
• Extended Data Frame:
• Remote Frame:
• Error Frame:
• Overload Frame:
• Interframe Space:

receiver and transmitter error states
for CAN1) 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 sends 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 can 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.
