Memory-Mapped I/O Registers
The USB 2.0 EHCI memory-mapped I/O space is composed of two sets of registers:
Capability Registers and Operational Registers.
memory range are ignored and result a master abort. Similarly, when the Memory
Space Enable (MSE) bit is not set in the Command register in configuration space, the
memory range will not be decoded by the Intel
Controller (EHC). When the MSE bit is not set, the Intel
allowing any memory accesses for the range specified in the BAR to go to PCI. This is

When set to ‘1’, this bit enables a select group of normally
read-only registers in the EHC function to be written by
software. Registers that may only be written when this mode
is entered are noted in the summary tables and detailed
description as Read/Write-Special. The registers fall into two
categories:
1. System-configured parameters
2. Status bits

BIOS should always program this register to the
recommended value of ‘111111b’. All other values are
