MC9S12 CAN bus message transmit only once

Hi,

I did a test with multi-CAN devices, and the S12 transmitted message per 250ms.

I obtained there is no ACK slot on waveform(no one received this message), thus the message was re-send again and again(the interval became only 1ms since message was re-sent nonstop).

 

I just want to know if there is a bit setting in register to ignore ACK or transmit only once, so that i can keep my message cycle time in 250ms.

 

thanks
