GENERAL CHARACTERISTICS
DESCRIPTION
SHARP IrDAContro Peripheral Enginewll exchangetheinfor-
mation wth μP through this serial interface(SS-Wre). Only two
attributes, ‘Command and‘Message, a simpesoftwarewll be
usedfor information transaction. Other protocol stacks aresup-
portedby PE andusers can simpy mnimzedesign effort andtime
TheSHARP IrDAContro Peripheral Engine(PE) is an
embeddedCommunication controler designedtofully support
IrDAContro MAC Layer andHID LLC Layer services. It has an
optimzedinterfacetoSHARP IrDAContro transcever andthe
Serial Interface(Synchronous Serial Wre) for μP
SinceIrDAContro MAC layer andHID LLC layer protoco stacks
arealready built-intoPE, onecan easily impement IrDAContro
Peripherals wth SHARP IrDAContro transcever andPE.
