In the example application codes used:

  • ‘Single Byte’ refers to 8-bit ADC data transmission.

  • ‘Multi Byte’ refers to SPI transmission capable of transmitting as many bytes as configured. In the examples, 2-byte data has been configured. Out of 16 bits transferred, only lower 12-bits contain ADC data since maximum resolution of ADC on MSPM0 is 12 bits.

  • ‘Single Channel’ refers that only 1 analog signal is monitored by ADC. Controller has to send a dummy command to initiate transaction, but command value need not be checked at peripheral.

  • ‘Multi Channel’ refers that ADC is converting multiple analog signals sequentially. Controller has to send a valid command to initiate transaction and receive corresponding channel data.
