2.5 AC and Timing Characteristics
2.5.1 16MHz Crystal Oscillator
The 16MHz Pierce crystal oscillator is designed for low power consumption and high stability operation. The 16MHz
oscillator can be trimmed without external capacitors. Two digital controlled trimming loading capacitors are integrated
and designed for the 12pF XTAL. Digital controlled capacitors could ease and speed up tuning procedure of XTAL frequency
accuracy.

2.5.2 32kHz RC Oscillator
The 32kHz RC oscillator is designed for low cost applications without additional external 32kHz XTAL. Due to characteristic
of RC oscillator, calibration is needed before switching to 32kHz RC oscillator mode.
