The HCAN2 Scheduler, which runs internal arbitration, has two states, Tx Arbitration State and
Rx Matching State. HCAN2 Scheduler is in the Rx Matching State if the CAN bus is in the EOF
or Intermission cycle, or otherwise is in the Tx Arbitration State. When a transmission (or
transmission abortion) request is made in the Tx Arbitration State, the internal arbitration starts
immediately. When a transmission (or transmission abortion) request is made in the Rx Matching
State, the internal arbitration waits until the Rx Matching State (i.e. Intermission field) is finished,
and then starts running as soon as the HCAN2 scheduler state becomes the ‘Tx arbitration state'.
There are 5 factors that can run internal arbitration, which are:
• CANTXPR is set.
• CANTXCR is set (not that, if CANTXCR is set for the message currently under transmission,
• Error occurs on the CAN bus.
HCAN2 does not stop the transmission but completes. If the message loses the bus arbitration
or causes an error on the bus, the HCAN2 will cancel the transmission request.)
