Slow Internal RC Oscillator Trim Configuration Register offset 0x20C.

Slow Internal RC Oscillator Trim Configuration Register offset 0x20CConfigures automatic trimming and calibration parameters for the SIRC oscillator to improve frequency accuracy and temperature stability.

慢速內部RC振盪器微調配置暫存器，改善頻率精度和溫度穩定性

Trim Configuration:

• Automatic trim enable/disable control
• Reference clock selection for trimming
• Trim update rate and settling time
• Temperature compensation parameters

註

Trimming Benefits:

• Improves frequency accuracy from ±10% to ±1-2%
• Reduces temperature drift effects
• Enables more precise low-power timing

• Automatic operation reduces software overhead

  Low-Power Clock:

  // Configure SIRC for maximum accuracy
  scg->sirctcfg = SIRC_AUTO_TRIM_ENABLE |
                  SIRC_TRIM_REF_SOSC |
                  SIRC_TEMP_COMPENSATION;
