caption_attribution_description: Creative Labs, Inc. Sound Blaster AWE32 PNP CT3990 with ASP chip FCC ID&#160;: IBACT-SBAPNP49 The CT3990 is the latest version of AWE32 with EMU-8000 wavetable synthesizer processor, and the latest Creative card that can use Advanced Signal Processor. Chips: CT1703 (CT1703-A) = 8/16-bit ADC/DAC Codec CT1741 (CT1741 V413) = Digital Sound Processor (DSP) v4.13 CT1745 (CT1745A-S) = Mixer chip CT1748 (CT1748-SBP) = Advanced Signal Processor (ASP) also known as: Creative Signal Processor (CSP) CT1749 (CT1749-DCQ) = Plug-and-Play ISA Bus interface chip CT1971 EMU-8000 (CT1971-Q) = E-mu wavetable synthesizer processor CT1972 EMU-8011 (CT1972Δ) = E-mu 1MB sample ROM CT1978 (CT1978-TAP) = CQM (Creative Quadratic Modulation) chip that largely emulate the features of the OPL-3 chip (the emulation of OPL-3 is far from perfect)
context_page_description: The term Legacy Plug and Play, also shortened to PnP, describes a series of specifications and Microsoft Windows features geared towards operating system configuration of devices. The standards were primarily aimed at the IBM PC standard bus, later dubbed Industry Standard Architecture. Related specifications are also defined for the common external or specialist buses commonly attached via ISA at the time of development, including RS-232 and parallel port devices.
  As a Windows feature, Plug and Play refers to operating system functionality that supports connectivity, configuration and management with native plug and play devices. Originally considered part of the same feature set as the specifications, Plug and Play in this context refers primarily to the responsibilities and interfaces associated with Windows driver development.
  Plug and Play allows for detection of devices without user intervention, and occasionally for minor configuration of device resources, such as I/O ports and device memory maps.

PnP is a specific set of standards, not be confused with the generic term plug and play, which describes any hardware specification that alleviates the need for user configuration of device resources.
