The MSPM0G3507 provides external clocks in addition to the internal clocks in the device.
The internal SYSOSC is 32 MHz by default at an accuracy of 2.5%. For higher accuracy, connect a 0.1% resistor at ROSC pin. The MCLK is sourced by 32MHz SYSOSC at default. CPUCLK is sourced directly from MCLK in RUN mode and disabled in other modes. The low-power clock (ULPCLK) can be sourced by MCLK and active in RUN and SLEEP mode by configuration. For more clock tree details, see Section 2.3 Clock Module (CKM) in the MSPM0 G-Series 80MHz Microcontrollers Technical Reference Manual.
