RX23W Group 36. CAN Module (RSCAN)

Transmit history function Stores the history information of transmitted messages.

Bus off recovery mode

selection

Selects a method of returning from bus off state.

 ISO 11898-1 compliant

 Automatic transition to channel halt mode at bus-off entry

 Automatic transition to channel halt mode at bus-off end

 Transition to channel halt mode by a program

 Transition to the error-active state by a program (forcible return from the bus off state)

Error status monitoring

 Monitors CAN protocol errors (stuff error, form error, ACK error, CRC error, bit error, ACK delimiter error,

and bus dominant lock).

 Detects error status transitions (error warning, error passive, bus off entry, and bus off recovery)

 Reads the error counter.

 Monitors DLC errors.
