CAN 2.0B Controller Module
16.3.5
The value of the free-running 16-bit timer is sampled at the beginning of the identifier field on the CAN
bus. For a message being received, the time stamp is stored in the time stamp entry of the receive message
buffer at the time the message is written into 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 message buffer 0. This
feature allows network time synchronization to be performed.
16.4
The basic operation of the TouCAN can be divided into four areas:
Example sequences for performing each of these processes is given in the following paragraphs.
