FlexRay active star coupler
- from Branch_TxOnly2 in response to a host ‘Branch_Normal’ command
- from Branch_TxOnly1 when a transmission ends without error
- from Branch_Disabled in response to a host ‘Branch_Normal’ command
- from Branch_Disabled when an overtemperature is resolved (TEMP_WARN = 0),
provided the overtemperature triggered the earlier transition to Branch_Disabled.
A branch switches from Branch_Normal:
- to Branch_FailSilent if a branch is clamped, provided clamp-detection is enabled
(CLAMP_DET = 1)
- to Branch_FailSilent if a transmit error is detected, provided bit AEC = 1
- to Branch_TxOnly2 if a host ‘Branch_TxOnly’ command is received
- to Branch_Disabled if an overtemperature event is detected (TEMP_HIGH = 1)
