(1) RBO (Return bus off) bit (D4)
The receive error counter (CANREC)/transmit error counter (CANTEC) can be cleared by setting
this bit to 1, thereby placing the CAN module forcibly in an error active state.
This bit is automatically cleared when an error active state is entered.
Note: After the error counters are cleared, the CAN module becomes ready to communicate
when 11 consecutive recessive bits are detected on the CAN bus.
(2) TSR (Time stamp counter reset) bit (D5)
Setting this bit to 1 clears the value of the CAN Time stamp Count Register (CANTSTMP) to
H'0000.
This bit is automatically cleared after the CAN Time stamp Count Register (CANTSTMP) has its
value cleared to H'0000.
(3) TSP (Time stamp prescaler) bits (D6, D7)
These bits select the count clock source for the time stamp counter.
Note: Do not alter the value set with these TSP bits while the CAN module is operating (CAN
Status Register CRS bit = 0).
(4) FRST (Forcible reset) bit (D11)
Setting this bit to 1 disconnects the CAN module from the CAN bus regardless of whether the
CAN module is communicating or not, with its protocol control unit reset.
Note 1: For CAN communication to be performed, the FRST and RST bits must be cleared to 0.
Note 2: If the FRST bit is set to 1 during communication, outputs at the CTX0 and CTX1 pins
become held high from that time on. Therefore, setting this bit to 1 while the CAN
module is sending a frame may cause a CAN bus error.
Note 3: The CAN Message Slot Control Register's transmit/receive request is not cleared by
setting the FRST or RST bit.
