Caution points:
*1. PT7C4337 uses 8 bits for address. For excess 0FH address, PT7C4337 will not respond (no acknowledge signal was given).
*2. Alarm 1 mask bits. Select alarm repeated rate when an alarm occurs.
*3. Alarm 2 mask bits. Select alarm repeated rate when an alarm occurs.
*4. Oscillator and time count chain enable/disable bit.
*5. Square wave output frequency select.
*6. Interrupt output pin select bit.
*7. Alarm 1 and alarm 2 enable bits.
*8. Alarm 1 and alarm 2 flag bits.
*9. Oscillator stop flag.
*10. All bits marked with "0" are read-only bits. Their value when read is always "0".
