Structure Elements

Item	Description
vs_netid	Network ID for the message
padding	Character used for padding to fill the rest of the last frame
id	ArbID of the message to look for
id_mask	Settable Mask for incoming ID
fc_id	ArbID for the flow control frame to send
flowControlExtendedAddress	Byte used for the extended address in outgoing flow control message
extendedAddress	Byte to be used for the extended address
blockSize	Number of frames to wait before sending another flow control frame
stMin	Seperation time to send for consecutive frames
cf_timeout	Timeout to wait for flow control
flags	Bit field containing flags for transaction Flag Value id_29_bit_enable: Enables 29 bit ID for ID to look for 1 fc_id_29_bit_enable: Enables 29 bit ID for Flow Control message. 2 ext_address_enable: Enables extended addressing to look for in Rx message 4 fc_ext_address_enable: Enables using an extended addressing byte in Flow Control frame 8 enableFlowControlTransmission: Enables sending a flow control frame 16 paddingEnable: enables padding for outgoing flow control frame 32 iscanFD: Sets transaction as CAN FD 64 isBRSEnabled: Enables Baud Rate Switch for CAN FD 128
