6.9.2 Oscillator and System Clock

The clock system in the MSP430xG461x family of devices is supported by the FLL+ module, which includes support for a 32768-Hz watch crystal oscillator, an internal digitally controlled oscillator (DCO), and a high-frequency crystal oscillator. The FLL+ clock module is designed to meet the requirements of both low system cost and low power consumption. The FLL+ features digital frequency locked loop (FLL) hardware that, in conjunction with a digital modulator, stabilizes the DCO frequency to a programmable multiple of the watch crystal frequency. The internal DCO provides a fast turnon clock source and stabilizes in less than 6 µs. The FLL+ module provides the following clock signals:

  • Auxiliary clock (ACLK), sourced from a 32768-Hz watch crystal or a high-frequency crystal
  • Main clock (MCLK), the system clock used by the CPU
  • Submain clock (SMCLK), the subsystem clock used by the peripheral modules
  • ACLK/n, the buffered output of ACLK, ACLK/2, ACLK/4, or ACLK/8
