MA101
Datasheet Version 1.02
5 Bridge Function Description
MA101's default mode is UART with the setting of Baud rate 4800, Even Parity Check and StopBit of 2. User
can use MA101_SetMode() function to change mode type or different mode setting in the BirdgeMini.DLL.
5.1 UART Mode
5.1.1 Feature
MA101 provides UART function as follow:
‹ Baud Rate : 4800, 9600, 19200, 38400, 51200, 57600, 102400 and 115200.
‹ Parity : None, Even and Odd
‹ Stop Bit : 1 bit, 1.5 bit and 2 bit
5.1.2 Initial and GPIO setting
When switch to UART Mode, Port 0.6 is UART_TX, initial setting is Open drain Output. Port 0.7 is UART_RX,
initial setting is high Impedance Input.
Initial Table as follow, others unchanged:

User can use MA101_SetIO_T(), MA101_SetIO_M(), and MA101_SetIO_V() function call in BridgeMini.DLL
to change GPIO setting as desired. Beware that during the data transmission, it is recommend not to Set
Mode; otherwise data might be lost. Also, before any data transmission, be sure the corresponding circuit
environment is built up.
When switch to UART Mode, the I/O configurations are allowed as follow:
