pub struct R { /* fields omitted */ }Value read from the register
Methods
impl R[src]
pub fn bits(&self) -> u32[src]
Value of the register as raw bits
pub fn adc(&self) -> ADCR[src]
Bit 0 - 64-bit Addressing Capability. If zero, no 64-bit addressing capability is supported.
pub fn pfl(&self) -> PFLR[src]
Bit 1 - Programmable Frame List Flag. If set to one, then the system software can specify and use a smaller frame list and configure the host controller via the USBCMD register Frame List Size field. The frame list must always be aligned on a 4K-boundary. This requirement ensures that the frame list is always physically contiguous.
pub fn asp(&self) -> ASPR[src]
Bit 2 - Asynchronous Schedule Park Capability. If this bit is set to a one, then the host controller supports the park feature for high-speed queue heads in the Asynchronous Schedule.The feature can be disabled or enabled and set to a specific level by using the Asynchronous Schedule Park Mode Enable and Asynchronous Schedule Park Mode Count fields in the USBCMD register.
pub fn ist(&self) -> ISTR[src]
Bits 4:7 - Isochronous Scheduling Threshold. This field indicates, relative to the current position of the executing host controller, where software can reliably update the isochronous schedule.
pub fn eecp(&self) -> EECPR[src]
Bits 8:15 - EHCI Extended Capabilities Pointer. This optional field indicates the existence of a capabilities list.
