Frequency Measurement Reset Control.

Frequency Measurement Reset ControlControls reset state of the Frequency Measurement (FREQME) peripheral. FREQME provides accurate measurement of clock frequencies using a reference clock, essential for clock monitoring and system diagnostics.

頻率測量重置控制，用於時脈頻率測量和診斷

FREQME Functions:

• Accurate frequency measurement using reference clock
• Multiple clock source selection for measurement
• Real-time clock monitoring and validation
• System clock integrity verification

註

Reset Effects:

• Measurement in progress is aborted
• Reference and target clock selections reset

• Measurement results registers cleared

  Monitoring:

  // Verify system clock frequency
  reset_ctrl.assert_reset(Control::FREQME);
  reset_ctrl.release_reset(Control::FREQME);
  uint32_t measured_freq = freqme_measure_clock(SYSTEM_CLOCK);
