13
(7) RST (CAN reset) bit (D15)
When the RST bit is cleared to 0, the CAN module is connected to the CAN bus and becomes
possible to communicate after detecting 11 consecutive recessive bits. Also, the CAN Time
stamp Count Register thereby starts counting.
When this bit is set to 1, the protocol control unit is reset and disconnected from the CAN bus
after sending frames from slots which have had transmit requests set. All frames received during
this time are processed normally.
Note 1: No new transmit requests can be set from when the CAN Status Register CRS bit is
set to 1 after setting the RST bit to 1 till when the protocol control unit is reset.
Note 2: When the protocol control unit is reset by setting the RST bit to 1, the CAN Time stamp
Count Register and CAN Transmit/Receive Error Count Register are initialized to 0.
Note 3: For CAN communication to be performed, the FRST and RST bits must be cleared to 0.
