• R
  Register hc_control_head_ed reader
• W
  Register hc_control_head_ed writer

Type Aliases

• EHCD_3_0_R
  Field ehcd_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.
• EHCD_31_4_R
  Field ehcd_31_4 reader - The HcControlHeadED register contains the physical address of the first Endpoint Descriptor of the Control list. HC traverse the Control list starting with the HcControlHeadED pointer. The content is loaded from HCCA during the initialization of HC.
• EHCD_31_4_W
  Field ehcd_31_4 writer - The HcControlHeadED register contains the physical address of the first Endpoint Descriptor of the Control list. HC traverse the Control list starting with the HcControlHeadED pointer. The content is loaded from HCCA during the initialization of HC.
