// 4.9 Recommended Power-Up Sequence
// 1. Hold RST low until the power supply and clocks are stable. In this state,
// the control port is reset to its default settings and VQ will remain low.
// 2. Bring RST high. The device will initially be in a low power state with VQ
// low. All features will default as described in the "Register Quick Reference"
// on page 40.
// 3. Perform a write operation to the Power Control register ("Power Control
// (Address 02h)" on page 43) to set bit 0 to a '1'b. This will place the
// device in a power down state.
// 4. Load the desired register settings while keeping the PDN bit set to '1'b.
// 5. Mute all DACs. Muting the DACs suppresses any noise associated with the
// CODEC's first initialization after power is applied.
// 6. Set the PDN bit in the power control register to '0'b. VQ will ramp to
// approximately VA/2 according to the Popguard specification in section
// "Popguard" on page 29.
// 7. Following approximately 2000 LRCK cycles, the device is initialized and
// ready for normal operation.
// 8. After the CODEC is initialized, wait ~90 LRCK cycles (~1.9 ms @48 kHz) and
// then un-mute the DACs.
// 9. Normal operation begins.
