The CMD_IDLE bit in the CPSW_PN_MAC_CONTROL_REG register allows MAC operation to be suspended. When the idle state is commanded, the MAC will stop processing receive and transmit frames at the next frame boundary. Any frame currently in reception or transmission will be completed normally without suspension. For transmission, any complete or partial frame in the TX cell FIFO will be transmitted. For receive, frames that are detected by the MAC after the suspend state is entered are ignored. No statistics will be kept for ignored frames. Commanded idle is similar in operation to emulation control and clock stop.
