User’s Manual

3. ARCHITECTURE OF ACT-IR100SD

The mandatory IrDA protocol layers, IrLAP and IrLMP (including IAS) are handled by ACT-IR100SD, In

addition, TinyTP, IrCOMM, IrLPT and OBEX transport are also included.

The incoming/outgoing IrDA user data payload are buffered and then transferred to/from the host. The

baud rates of IrDA traffic and host interface are independent of each other. The flow controls of IrDA

traffic and host interface are also independent of each other.
