Note (1): User can set UART_TX to 0 or 1 by MA101_SetIO_V() for special application. It is recommended not
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.
Note (2): If there is an EEPROM with Customer’s ID Data, user can’t change any setting on Port 2.1 and Port
2.2 by DLL Function Library. The setting includes Input/Out, CMOS/NMOS, Pull High Resistor
Enable/Disable and Output Value. On the contrary, if there is no EEPROM, Port 2.1 and Port 2.2 are
free to change by user.
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.

5.3.3 SPI Setting and Data Flow
MA101
Datasheet Version 1.02
Figure 5-5 : SPI waveform diagram
Parameter definition in SPI
Data_Priority
0 : LSB of data is transmitted first
1 : MSB of data is transmitted first
Fetch
0 : Fetch data on CLK falling
1 : Fetch data on CLK rising
Clk
0 : CLK in LOW when IDLE
1 : CLK in HIGH when IDEL
Clock_Rate 0x00~0xFF for clock period
5.3.4 SPI AC Electrical Characteristics
User can use MA101_SetMode() function call in BridgeMini.DLL to change SPI data rate setting as desired.
Example : Fetch data on CLK falling, Write data on CLK Rising
