CHAPTER 19 FCAN CONTROLLER (V850/SC3)
Table 19-20. Operation in Error Status
When the bus is idle, the transmit enable mode is set for each node. Transmission then starts
from a node.
After the 8-bit bus idle field (suspend transmission), the transmit enable mode is set. Receive
mode is set if a transmission starts from a different node in bus idle mode (the transmission
priority of the local node is lowered).
A receive operation is performed when start of frame output by the other node is detected.
The identifier is transmitted when start of frame output by the local node is detected.
