Note:
Transmit Error Counter Register (TECR)
Read only
Reset value: 0000 0000 (00h)
TEC[7:0] is the least significant byte of the 9-bit transmit error counter implementing part of
the fault confinement mechanism of the CAN protocol.
Receive Error Counter Register (RECR)
Page: 00h — read only
Reset value: 0000 0000 (00h)
REC[7:0] is the receive error counter implementing part of the fault confinement mechanism
of the CAN protocol. In case of an error during reception, this counter is incremented by 1 or
by 8 depending on the error condition as defined by the CAN standard. After every
successful reception the counter is decremented by 1 or reset to 120 if its value was higher
than 128. When the counter value exceeds 127, the CAN controller enters the error passive
state.
CAN diagnosis register (CDGR)
Read/ write
Reset value: 0000 1100 (0Ch)
All bits of this register are set and cleared by software.
Bit 3 = RX CAN Rx Signal
Read
Monitors the actual value of the CAN_RX Pin.
Bit 2 = SAMP Last Sample Point
Read
The value of the last sample point.
Bit 1 = SILM Silent Mode
