1.5.1 TransparentTransmissionMode
ALX41X modules support serial interface transparent transmission mode. The benefit of this
mode is achievesa plug and playserial dataport, and reduces user complexity furthest.In  this
mode, user should only configure the necessary parameters. After power on, module can
automaticallyconnecttothedefaultmaster.
1.5.2 ConfigurationMode
Inconfigurationmode,usercanfinishALX41Xmoduleconfigurationmanagementand
parameterssettingwork. PleaserefertothedataformatofthedocumentprovidedbyAlinket,
alsoyoucandefineyourowndataformat.
1.5.3 GPIOPort
The ALX41X has 10 general‐purpose I/Os (GPIOs) in the 21‐pin package. All GPIOs support
programmablepull‐upandpull‐downresistor s,andallsupporta2mAdrivestrengthexceptP26,
P27,andP28,whichprovidea16mAdrivestrengthat3.3Vsupply.
ThefollowingGPIOsareavailable:

•
SPI_2:MOSI(P0,A/D)
• ADC2(P1,IR_TX,SPI_2:MISO(master&slave))
• PRXD(P2,
