Indicated by
The CC strobes every protocol state change
(see
(PSR)”).
The CC strobes every static slot start.
The CC strobes every minislot start.
This function outputs data received on channel
A RxD (RXD_BG1/RXD1_485 pin) after glitch
filter processing.
The CC strobes every dynamic slot start on
channel A.
The CC strobes every receive frame start on
channel A.
The CC indicates every reception of a
syntactically correct and semantically valid
frame on channel A after 11 FlexRay bus bits,
measured from the received frame end
sequence.
The CC strobes every communication cycle
start with a rising edge. This signal stays high
during the communication cycle and the CC
negates it (low) with the NIT start.
This function outputs the CC internal corrected
macrotick.
The CC strobes the time point during the NIT
when it performs the offset correction.
This function outputs data received on channel
B RxD (RXD_BG2/RXD2_485 pin) after glitch
filter processing.
The CC strobes every dynamic slot start on
channel B.
The CC strobes every receive frame start on
channel B.
The CC indicates every reception of a
syntactically correct and semantically valid
frame on channel B after 11 FlexRay bus bits
measured from the received frame end
sequence.
