7 Key Digital Peripherals

The MSPM0G series MCU includes a wealth of digital peripheral resources, like Timer, UART, SPI, MCAN, LIN etc. which provide rich communication capabilities. To maximize the use of the MSPM0G's digital peripherals, some considerations need to be made in the hardware design. This chapter discusses design considerations for many typical digital peripheral configurations.
