POWER-ON RESET
When power is initially applied to the device supply pin, a power-on reset sequence is executed, similar
to that which occurs when the device is restored from a power-down condition. This sequence comprises
two stages, first a conventional POR to initialize all on-chip circuitry, followed by a stabilization period
to allow the oscillator to reach a stable frequency before enabling the outputs:
1. Initialize internal circuitry.
2. Enable internal oscillator.
3. Set M and N to maximum values.
4. Wait approximately 256 cycles of MCLK for the oscillator to stabilize.
5. Load M and N programmed values from EEPROM.
6. Enable OUT0 (if enabled).
7. Enable OUT1.
