that enables i2s if ENB is set and RST is not set.

The fix looks fine, but the resulting code is probably over
engineered... What about:
s->enable = (value & 9) == 1;
?

Can you please provide a new version with that code instead, I'll apply
it.

RST bit is (1 << 4) bit, not (1 << 3), fix condition
that enables i2s if ENB is set and RST is not set.
