This block consists of transmit logic, Cyclic Redundancy Check (CRC) generator module, transmit data MUX, TX First In First Out (FIFO) and the transmit interface module. The CRC generator module calculates the CRC for the frame to be transmitted. The transmit control MUX arranges this frame and sends the preamble, Start-of-Frame Delimiter (SFD), frame data, padding and CRC to the transmit FIFO in the required order. When the frame is transmitted to the PHY, this module generates a transmit interrupt and updates the transmit control register.
