usbsts: Single<UsbStatusRegister, M>

USB Status Register

pagesize: Single<PageSizeRegister, M>

Page Size Register

crcr: Single<CommandRingControlRegister, M>

Implementations

impl<M> Operational<M> where
    M: Mapper + Clone, 

pub unsafe fn new(
    mmio_base: usize,
    caplength: CapabilityRegistersLength,
    mapper: &M
) -> Result<Self, Error> where
    M: Mapper, 

Creates a new accessor to the Host Controller Operational Registers.

Safety

The caller must ensure that the Host Controller Operational Registers are accessed only through this struct.

Errors

This method may return an accessor::Error::NotAligned error if mmio_base is not aligned.
