- Direction of the object (please also see table below):
- DIR = 1: transmit Data Frames; receive and answer Remote Frames
- (in the following called "transmit object"),
- DIR = 0: transmit Remote Frames; receive Data Frames
- (in the following called "receive object")

Example for a Standard CAN transmit object with 8 bytes data length:
C167CR / C515C:
MCFG_Mn = 0x88; /*Mess. Configur. Reg. n (EFn6h/F7n6h)*/
/* 1 0 0 0 1 0 0 0 */
/*|<-DLC->| D X - - */
