• Manufacturer Part Number: ma101-ts28
• Description: Ma101 Is A Driver Free Usb Data Bridge
• Manufacturer: Megawin Technology

Note (1): User can set UART_TX to 0 or 1 by MA101_SetIO_V() for special application. It is recommended not
Note (2): If there is an EEPROM with Customer’s ID Data, user can’t change any setting on Port 2.1 and Port
5.1.3 Buffer Busy Indicator
When MA101 Data Rx Buffer is near full, Port 0.0 (Busy LED) will change to LOW, remind DUT slow down or
stop transfer data to MA101; otherwise, MA101 Rx Data Buffer will overrun. Port 0.0 (Busy LED) will return to
HIGH when MA101 Rx Buffer is not busy and safe to continue receive data from Backend Device.
Note: Under certain circumstances, if system resources are not available, it is necessary to reference P0.0
(busy pin) to avoid the data lost.

free to change by user.
to call MA101_SetIO_V() function during the data transmitting; otherwise, the result is undefined.
MA101 will reset UART_TX to 1 before transferring any data through WriteData() api, and it keeps 1
after data is completed.
