Struct moa_core::Bus

pub struct Bus {
    blocks: Vec<Block>,
    ignore_unmapped: bool,
    watchers: Vec<Address>,
    watcher_modified: bool,
}

A bus-like collection of Addressable Devices mapped to different address ranges

This is the fundamental means of connecting devices together to a CPU implementation.

Fields

blocks: Vec<Block>

ignore_unmapped: bool

watchers: Vec<Address>

watcher_modified: bool
