I try to judge whether the data has been transferred from IF1 registers to message RAM before writing new data to IF1 registers, based on the value of "busy" bit in the IF1CMD register. However, I found that the "busy" bit is not even set after message object number is written to bits 7:0 of the IF1CMD register, which disagrees with the techinical reference document. I have also test the "can_ex4_simple_transmit" project in C2000Ware examples and got the same issue. Why?
