Host Control Driver Interface(HCI) Functions

4.1 Functions and Features
For the case of uITRON, until the drive is mounted, HCI uses the HCD class area to send and receive messages.
When mounting of the drive is finished, it uses the HMSCD dedicated area. For the case of non-OS,HCI uses the
HMSCD area to send and receive messages. And it is not possible to enumerate (or access) two devices simultaneously.
4.2 HCI Global Area
Table 4.1 lists details of the HCI global area.
