Doubt abt Minimum cycle transmit period for a CAN message with 500kbps

Hello everyone,

 

I want to confirm a scenario about .... the minimum transmit cycle period for my CAN Tx message.

For example, if I have a board with say HCS12(X) family MCU with 8 MHz crystal supporting the High speed CAN transceiver with 500 Kbps. Then what is the possible minimum cycle period for a CAN Tx message with 8 bytes of data length?

 

My assumption is .. since my baud rate is 500 kbps. So, the time to transmit a single bit to the CAN bus is (1/500 kbps) i.e. 2us. So, to transmit 8 bytes of Tx message, it can be 8*8*2us = 128us. So, can I send this CAN message from my board with a cycle period of say 200usec (which is below the 128us). ???

 

 Thankyou
