USER’S MANUAL
that buffer. For a message being transmitted, the time stamp entry is written into the
transmit message buffer once the transmission has completed successfully.
The free-running timer can optionally be reset upon the reception of a frame into mes-
sage buffer 0. This feature allows network time synchronization to be performed.
The basic operation of the TouCAN can be divided into three areas:
Example sequences for performing each of these processes is given in the following
paragraphs.
The TouCAN can be reset in two ways:
Following the negation of reset, the TouCAN is not synchronized with the CAN bus,
and the HALT, FRZ, and FRZACK bits in the module configuration register are set. In
this state, the TouCAN does not initiate frame transmissions or receive any frames
from the CAN bus. The contents of the message buffers are not changed following re-
set.
Any configuration change or initialization requires that the TouCAN be frozen by either
the assertion of the HALT bit in the module configuration register or by reset.
Initialization of the TouCAN includes the initial configuration of the message buffers
and configuration of the CAN communication parameters following a reset, as well as
any reconfiguration which may be required during operation. The following is a general
initialization sequence for the TouCAN:
• Reset and initialization of the module
• Transmit message handling
• Receive message handling
• Hard reset, using one of the IMB3 reset lines
• Soft reset, using the SOFTRST bit in the module configuration register
1. Initialize all operation modes
2. Initialize message buffers
