7.2.4
Auto-CTS (Transmitter Control)
In this mode the CTS input pin controls the transfer from internal buffer (X or Y) to theTDR. When the DMA controller
transfers data from the Y-buffer to the TDR and the CTS input pin goes high, the DMA controller is suspended until
CTS goes low. Meanwhile, the UBM is transferring data from the host to the X-buffer. When CTS goes low, the DMA
resumes the transfer. Data transfer continues alternating between the X and Y buffers, without MCU intervention. See
section 6.2 for DMA transfer termination condition.
7.2.5
Xon/Xoff Receiver Flow Control
To enable Xon/Xoff flow control, certain MCR bits must be set as follows: MCR[5] = 1 and MCR[7:6] = 0. In this mode,
the Xon/Xoff bytes are transmitted to an external sending device to control the device’s transmission. When the
high-level mark (of the FIFO) is reached, the Xoff byte is transmitted, signaling to an external sending device to halt
its transfer. Conversely, when the low-level mark is reached, the Xon byte is transmitted, signaling to an external
sending device to resume its transfer. Data transfer from the FIFO to X/Y-buffer is performed by the DMA controller.
7.2.6
Xon/Xoff Transmit Flow Control
To enable Xon/Xoff flow control, certain MCR bits must be set as follows: MCR[5] = 1 and MCR[7:6] = 0. In this mode,
the incoming data are compared to the XON and XOFF registers. If a match to XOFF is detected, the DMA is paused.
If a match to XON is detected, the DMA resumes. Meanwhile, the UBM is transferring data from the host to the
X-buffer. The MCU does not switch the buffers unless the Y-buffer is empty and X-buffer is full. When Xon is detected,
the DMA resumes the transfer.
