Item Specification
Bus off recovery mode
selection
Selects a method of returning from bus off state.
• ISO11898-1 compliant
• Automatic entry to channel halt mode at bus-off entry
• Automatic entry to channel halt mode at bus-off end
• Entry 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.
Interrupt source 6 sources
• Global (2 sources)
CAN global receive FIFO interrupt
CAN global error interrupt
• Channel (4 sources/channel)
CANi channel transmit interrupt
CANi transmit complete interrupt
CANi transmit abort interrupt
CANi transmit/receive FIFO transmit complete interrupt
CANi transmit history interrupt
CANi transmit/receive FIFO receive interrupt
CANi channel error interrupt
CANi wakeup interrupt
CAN stop mode Reduces power consumption by stopping clock supply to the CAN module.
CAN clock source Selects the clock obtained by frequency-dividing fCLK by 2 (fCLK/2) or the X1 clock (fx).
Test function Test function for user evaluation
• Listen-only mode
• Self-test mode 0 (external loopback)
• Self-test mode 1 (internal loopback)
• RAM test (read/write test)
