11.3.Asynchronous Packet Transmitting

The example of control flow for transmitting of Asynchronous packet is shown below.

<Flow chart before storing transmitting data into Asynchronous transmit FIFO

<Host>

START

Write one word the data to be

transmitted in Asynchronous transmit

data port.

Number of residual transfer byte = Number of residual transfer byte –(minus) 2.

<Device>

Write data for 1 word for

Asynchronous transmit buffer and

increment the write pointer.

Number of residual transfer

byte > 0

END

Figure 11.3.1 Flow chart before storing transmitting data in Asynchronous transmit FIFO

Note1: Store the data to be transmit previously in Asynchronous transmit FIFO.

Note2: If the transmitting length is below the digit of quadret, write “0” there up to quadret unit.

Note3: The device can automatically attaches CRC code.
