CRC for CAN frame in STM8AF5286

[PPate.1]

I am using STM8AF5286 for one of my design. I am using CAN port for data transmission. I am using standard ST library for CAN communication. I don't see any 16-bit CRC calculation included in CAN_Transmit function of CAN driver function. Neither I see any CAN controller register where CRC is to be stored. How CRC is calculated and transmitted in CAN packet by STM8AFxx?
