Struct moa_core::memory::BusPort

pub struct BusPort {
    offset: Address,
    address_mask: Address,
    data_width: u8,
    subdevice: Rc<RefCell<Bus>>,
}

An adapter for limiting the access requests of a device (eg. CPU) on a Bus to the address and data widths of the device

Fields

offset: Address

address_mask: Address

data_width: u8

subdevice: Rc<RefCell<Bus>>
