Notes:
1. Below 1 KHz the clock loss detect circuit may power down the chip. If the clock loss detect circuit is
disabled (address 1, bits 14 and 15) 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.
