GENERAL DESCRIPTION
It also provides support for power management (including a WATCHDOG timer) and standard PC-AT address decoding for on-chip functions. The Plug and Play (PnP) support in the device conforms to the “Plug and Play ISA Specification” Version 1.0a, May 5, 1994. The Infrared (IR) interface complies with the IrDA 1.0 SIR and SHARP-IR standards, and supports all four basic protocols for Consumer-IR (TV-Remote) circuitry (RC-5, RC-5 extended, RECS80 and NEC).
