IFn Command Request Register (CAN_IFn_CREQ)
Register
CAN_IFn_CREQ CAN0_BA+0x20/0x80 R/W
Bits
[15]
[14:6]
[5:0]
A message transfer is started as soon as the application software has written the message
number to the Command Request Register. With this write operation, the Busy bit is
automatically set to notify the CPU that a transfer is in progress. After a waiting time of 3 to 6
APB_CLK periods, the transfer between the Interface Register and the Message RAM is
completed. The Busy bit is cleared.
Note: When a Message Number that is not valid is written into the Command Request
Register, the Message Number will be transformed into a valid value and that Message Object
will be transferred.

1 = Writing to the IFn Command Request Register is in progress. This bit can only be read
0 = Read/write action has finished.
Reserved
There are reserved bits. These bits are always read as ‘0’ and must always be written with
‘0’.
