DESCRIPTION
-----------
This product is the Nuvoton Generic HID driver installation package for the
Nuvoton EC devices.
This installation package contains the following driver:
Nuvoton EC Windows 7-Based Generic HID 32/64-bit Driver
Version: 8.1.81.1000
BIOS PnP ID: WEC1040
The driver implements:
Generic HID functionality
The Windows-based driver is designed to work with the EC firmware (FW),
which implements Generic HID support.
See the next section (REQUIREMENTS) for details.
REQUIREMENTS
------------
* Operating System:
32/64-bit Windows 7
* Hardware:
A platform containing a Nuvoton EC device with appropriate firmware and
PnP BIOS.
- The EC FW should support Generic HID functionality, as implemented in
the latest Nuvoton EC FW release.
The EC FW is provided in a separate package.
For a detailed description of the EC FW functionality, see its
documentation.
* BIOS:
The BIOS should require the following resources for the device with PnP
ID ACPI/WEC1040 and configure the EC's corresponding LDN/s accordingly:
- One IRQ to be configured (as Level) in a selected PM channel's LDN
- One of two alternative communication methods - PM channel or SHM, as
follows:
For PM channel:
Two I/O addresses (size 1 byte each). The lower address is used for
the Data Register Base Address.
For SHM:
2,4,8,16 or 32 bytes of consecutive memory or consecutive I/O.
If SHM-IO is used, an appropriate bit in SHM LDN should be set.
Note 1: The IRQ is allocated and configured for the PM channel even
when the SHM communication method is used.
Note 2: Shared Memory Window #1 should be used, since Window #2 is
reserved for Flash Update.
Note 3: The BIOS should enable host access to HCBAH/HCBAL I/O
addresses even after the POST stage.
* Firmware:
There are two requirements from the EC firmware to support the EC
Generic HID driver:
- Provide Host Configuration Address to the driver (details below)
- Send HID reports in specified format (details below)
The exact protocol in which both requirements are performed depends on
whether the PM channel or Shared Memory is used to communicate between
the FW and driver.
