The controller enters sleep mode from configuration or normal mode when the Mode_Select [SLEEP] bit is set = 1, CAN bus is idle, and there are no pending transmission requests.

The controller enters configuration mode when any configuration condition is satisfied.

When the controller wakes up, it clears the Mode_Select [SLEEP] request bit and also clears the corresponding status bit. The controller enters normal mode under the following wake-up conditions:

  • [SLEEP] is set = 0
  • [SLEEP] bit is = 1, bus activity is detected
  • New message are posted for transmission

Interrupt bits are set when the controller enters or wakes up from sleep mode.
