Power up with RAMP-UP (PU2-C5H) or without RAMP-UP (PU1-8DH)
1. PU1 (C5H) will power-up the chip and set the COUT to 80H immediately and stay
2. PU2 (8DH) will Ramp-up chip and ramp-up COUT from 00H to 80H and stay there.
3. Power-up will start after 350us (at 6KHz sampling rate).
4. Voice will be playback immediately after PU1 / PU2 completes if the section buffer
5. OUT1 (BUSY) will output logic HIGH during Ramp-up operation.
6. PDN2 (Power-down with ramp-down) will be executed correctly only if PU2 is
