CAN Channel
Configuration
CAN Data Buffers
The CAN channel can be in:
Buffer MOb i
Buffer MOb2
Buffer MOb1
Buffer MOb0
• Enabled mode
• Standby mode
• Listening mode
– the CAN channel (internal TxCAN & RxCAN) is enabled,
– the input clock is enabled.
– the transmitter constantly provides a recessive level (on internal TxCAN) and the
– input clock is enabled,
– the registers and pages remain accessible.
In this mode:
In standby mode:
This mode is transparent for the CAN channel:
receiver is disabled,
