2.8 Clock

The interrupt polarity (active high/low) can be configured with INT_MASK register's INT_ACT bit.
Once the interrupt has happened, the INT_STATUS register must be read to acknowledge the
interrupt.
See section 3.3 for INT_STATUS register details.
The SCA3000 has an internal factory trimmed oscillator and clock generator. Internal frequencies
vary product by product.
1. If at least one of MD bits in INT_STATUS register is "1", motion has been detected.
2. If FFD bit in INT_STATUS register is "1", free-fall has been detected.
3. If BUF_FULL bit is "1", Ring Buffer is 75% full. Correspondingly, if BUF_HALF is "1", the
Ring Buffer is 50% full.
