PTD if the HCD has reset its corresponding skipped bit to logic 0. Clearing the
corresponding bit in the HcINTLPTDSkipMap register when there is no valid data in the
block will cause unpredictable behavior of the Host Controller.
Code (Hex): 18 — read
Code (Hex): 98 — write
This is a 32-bit register, and
represents the first PTD stored in the INTL buffer, bit 1 represents the second PTD stored
in the buffer, and so on. The bit that is set to logic 1 by the HCD is used as an indication to
the Host Controller that its corresponding PTD is the last PTD stored in the INTL buffer.
When the processing of the last PTD is complete, the Host Controller proceeds to process
ATL transactions.
Code (Hex): 19 — read
Code (Hex): 99 — write
This register indicates which PTD stored in the INTL buffer is currently active and is
updated by the Host Controller. The HCD can use it as a buffer pointer to decide which
PTD locations are currently free to fill in new PTDs to the buffer. This indication is to
prevent the HCD from accidentally writing into the currently active PTD buffer location.
