Structs

• HC_BULK_HEAD_ED_SPEC
  OHCI Bulk Head ED Base
• R
  Register hc_bulk_head_ed reader
• W
  Register hc_bulk_head_ed writer

Type Aliases

• BHED_3_0_R
  Field bhed_3_0 reader - Because the general TD length is 16 bytes, the memory structure for the TD must be aligned to a 16-byte boundary. So the lower bits in the PCED, through bit 0 to bit 3 must be zero in this field.
• BHED_31_4_R
  Field bhed_31_4 reader - The HcBulkHeadED register contains the physical address of the first Endpoint Descriptor of the Bulk list. HC traverses the Bulk list starting with the HcBulkHeadED pointer. The content is loaded from HCCA during the initialization of HC.
• BHED_31_4_W
  Field bhed_31_4 writer - The HcBulkHeadED register contains the physical address of the first Endpoint Descriptor of the Bulk list. HC traverses the Bulk list starting with the HcBulkHeadED pointer. The content is loaded from HCCA during the initialization of HC.
