The MT6660 is a boosted BTL class-D amplifier with V/I sensing. A built-in DC-DC step-up converter is used to provide efficient power for class-D amplifier with multi-level class-G operation. The digital audio interface supports I2S, left-justified, right-justified, TDM and DSP A/B format for audio in with a data out used for chip information like voltage sense and current sense, which are able to be monitored via DATAO through proper

packed structures could have been better.
It depends. Packing may break alignment and the performance may suffer from it. So, in general, __packed is recommended when the size matters (e.g. lots of objects / arrays are created) or it's about ABI that needs the fixed consistent size.
