The HcHCCA register contains the physical address of Host Controller Communication
Area (HCCA). The bit allocation is given in
restrictions by writing all 1s to HcHCCA and reading the content of HcHCCA. The
alignment is evaluated by examining the number of zeroes in lower order bits. The
minimum alignment is 256 bytes; therefore, bits 0 through 7 will always return logic 0
when read. This area is used to hold the control structures and the interrupt table that are
accessed by both the Host Controller and the HCD.
Description
Host Controller Communication Area Base Address: This is the base address of the HCCA.
-
The HcPeriodCurrentED register contains the physical address of the current isochronous
or interrupt ED.
