Figure 23.18 C0MDR Register
23.1.16 CAN0 Mode Register (C0MDR Register)
22.214.171.124 CMOD Bit
The CMOD bit selects a CAN operating mode.
• Normal operating mode: The CAN module transmits and receives data successfully.
• Bus monitoring mode
• Self-test mode: The CAN module connects the CAN0
CAN0 Mode Register
1. Do not generate a transmit request in bus monitoring mode.
The CAN module assumes the ACK bit is set to dominant "L" regardless of the ACK bit setting.
Therefore, when the CRC delimiter is received successfully, the CAN module determines the
data is received with no error regardless of the ACK bit setting.
1. Set the C0MDR register when the STATE_RESET bit in the C0STR register is set to "1" (CAN
2. Value is obtained by setting the SLEEP bit in the C0SLPR register to "1" (sleep mode exited) after
module reset completed).
