Trait AudioBus 

pub trait AudioBus {
    // Required method
    fn ai_dma_read_u32(&self, addr: u32) -> u32;

    // Provided method
    fn raise_ai_interrupt(&mut self) { ... }
}

The narrow bus the AI sees (RustyNES’s ApuBus analog): fetch a DMA sample word from RDRAM and raise the AI interrupt when a buffer starts.

Required Methods

fn ai_dma_read_u32(&self, addr: u32) -> u32

Fetch a big-endian 32-bit sample word (two 16-bit L/R samples) from the AI DMA buffer in RDRAM at addr.

Provided Methods

fn raise_ai_interrupt(&mut self)

Raise the AI interrupt on the MI (a queued buffer became active). Default no-op so a non-interrupt bus can still drive the DAC.
