Abstract
A LAN adapter is implemented in the communication system to selectively exclude four bytes of the CRC value appended to an end of a frame's information field through the use of a configuration bit in a register. By programming this configuration bit to have a specific logic value, the four-bytes of the CRC value may be selectively copied, together with the data in the frame, into a destination computer system's main memory. Additionally, regardless of the setting of this configuration bit, the four-bytes of the CRC value will always be used to check the integrity of the data in the frame. Stated another way, the configuration bit will only affect whether the four-bytes of the CRC value will be transferred as part of the frame after the CRC check operation has been performed.
