CAN RTR feature

We tried to use RTR feature. Sending RTR frames is OK, but I can't send RTR answer frame automatically (by hardware support).
MSCAN user manual says that:

This flag reflects the status of the Remote Transmission Request bit in the CAN frame. In the case of

a receive buffer, it indicates the status of the received frame and supports the transmission of an

answering frame in software. In the case of a transmit buffer, this flag defines the setting of the RTR

bit to be sent.

What is the meaning of software? (Does freescale MSCAN not support automatic RTR answering?)

Thanks in advance.
