Notes:
1. Below 1 KHz the clock loss detect circuit will power down the chip. If the clock loss detect circuit is
disabled (bit 5, address 7) and the clock is stopped, the chip may draw up to one Amp of power supply
current for approximately 10 seconds. After 10 seconds the current will go down to below 50 mAmps.
