USB Interface
HT82K629A has one control pipe for USB configuration, command and status type communication flows between cli-
ents software (BIOS, Win 98, Win 2K, Win ME and Win XP etc.) and HT82K629Akeyboard encoder device. It also has
two interrupt pipes to send the HID page 7 Standard keyboard code and ACPI, multimedia key correspondingly to cli-
ents software. For LED output, it comes from the control pipe.
HT82K629A can support USB standard request and HID class request. It is shown in the following table:

Keyboard Output Format for USB Interface
Endpoint1
The Endpoint1 of HT82K629Ais used to send standard keyboard key code and is configured as interrupt pipe. It con-
tain 8 bytes data. The first byte is a modified byte to send the left and right of the (Shift, ALT, CTRLand WIN) key sta-
tus. It is in bitmap format. The second byte is a reserved byte. The third to eight bytes are used to send the other HID
page7 key codes (except for the above modified key). The key code list is shown as the USB HID standard keyboard
code table.
