Struct gba_hal::data::NoiseFrequencyControl

#[repr(transparent)]
pub struct NoiseFrequencyControl(_);

Noise channel frequency and master control setting

Frequency is 524288 / r / 2^(s+1) Hz. For r=0 assume r=0.5 instead.

• 0-2: divide ratio r
• 3: Use a 7-bit counter (true) or 15-bit counter (false)
• 4-7: shift clock frequency s
• 14: Stop output when length expires
• 15 (wo): Initialize / restart the sound.
