Document Table of Contents Collision Detection in Half-Duplex Mode

In half-duplex mode, the MAC function checks for collisions during frame reception. When collision is detected during the reception of the first 64 bytes, the MAC function discards the frame if the RX_ERR_DISC bit is set to 1. Otherwise, the MAC function forwards the frame to the user application with error.
