Endpoint for IrDA Control. Both ends of the communication flow between the USB Dongle and
IrDA Control Peripherals.
Host devices that perform IrDA Control Host function. (ex. USB Dongle)
Peripheral devices that perform IrDA Control Peripheral function, or peripheral devices where
IrDA Control capability is implemented.
Logical Link Control. One of the protocol layers defined in IrDA Control standard.
Media Access Control. One of the protocol layers defined in IrDA Control standard.
Operation request given by IrDA Control communication LSI to system μP over SS-Wire.
Message ID.
Non-Critical Latency. One of the parameters used to categorize the attributes of the IrDA Con-
trol Peripheral (opposite of CL).
Peripheral Engine. An embedded IrDA Control communication controller to implement the
IrDA Control Peripheral, offered by Sharp (P/N: LZ85194).
Address assigned for the peripheral.
Specific information unique to the peripheral.
Peripheral Physical Identifier. Used to identify the IrDA Control Peripheral.
Communication method where the Host inquires the existence of data to the plural peripher-
als one at the same time in certain order.
Access point where the peripherals are connected.
The external peripheral to shift the operation mode of the Host, from Suspend to the normal
operation mode.
Packet sent by IrDA Control Peripheral to request Enumerate or Bind with the Host. Host iden-
tification information (HostID, HostInfo) must be obtained prior to sending Request Packet.
Packet sent by the USB Dongle to inform IrDA Control Peripheral that it has completed the
Enumeration or Bind by the Request Packet.
Sharing single Endpoint over plural IrDA Control Peripherals.
Synchronous Serial Wire. Serial interface provided to the IrDA Control Communication Con-
troller (example: PE) to connect with the system μP.
One of the operation modes, in stand-by, with least power consumption.
Packets executed on the USB Bus (IN and OUT packet).
Communication status where the Enumeration is completed, but the infrared data transaction
by polling is not taking place between a Host and the IrDA Control Peripheral (opposite of Bind).
Status in which Enumeration is not completed. IrDA Control Peripherals can be forced to
‘
UnEnumerated
’
by issuing RESET command to PE.
Equipment that has USB interface. It can not only be peripherals, such as keyboard or mouse,
but anything that performs the Host functions.
An external adapter with USB interface that implements the whole IrDA Control system.
Endpoint for USB. Both ends of the communication flow between the Host (PC) and USB Dongle.
A Device on the Host that performs the USB functions.
Peripherals that have USB interface (example: USB keyboard, or USB mouse) USB
Request commands sent by the Host to USB Dongle for data transaction and its control.
USB Dongle to inform Dongle Driver of the connected IrDA Control Peripherals

supply volt-
age status. The supply voltage information is prepared mainly for the end-users to acknowl-
edge the battery level of the IrDA Control Peripheral in use.
Packet sent by IrDA Control Peripheral to request USB Dongle for the polling, so that the IrDA
Control Peripheral can execute the required procedures for Enumeration or Bind with the Host.
