POWER-DOWN CONTROL
POWER-DOWN
If PDN is taken low a power-down sequence is initiated. The “Enabling Sequencer” is used to execute
events in the following sequence:
1. Disable OUT1 (same sequence as when OE is used) and reset N counters.
2. When OUT1 is low, switch OUT1 to high-impedance state.
3. Disable MCLK, switch OUT0 to high impedance state.
4. Disable master oscillator.
POWER-UP
When PDN is taken to a high level the following power-up sequence occurs:
1. Enable internal oscillator.
2. Set M and N to maximum values.
3. Wait approximately 256 cycles of MCLK for it to stabilize.
4. Reset M and N to programmed values.
5. Enable OUT0 ( if enabled)
6. Enable OUT1.
Steps 2 through 4 exist to allow the oscillator to stabilize before enabling the outputs.
