Preliminary
OPL3 Single-chip Audio System 3
OUTLINE
YMF715E-S (OPL3-SA3) is a single audio chip that integrates OPL3 and its DAC, 16bit Sigma-delta
CODEC, MPU401 MIDI interface, joystick port, and a 3D enhanced controller including all the analog
components which is suitable for multi-media application. This LSI is fully compliant with Plug and Play
ISA 1.0a, and supports all the necessary features, i.e. 16bit address decode, more IRQs and DMAs in
compliance with PC’96. This L

YMF715E 2. ISA Interface OPL3-SA3 supports ISA Plug and Play (PnP) that frees the users from configuring the I/O address, IRQ and DMA channel. Those system resources are set automatically by the system. However even when used in Non PnP system, the configuration can be changed with software. 2-1. PnP Auto-Configuration mode OPL3-SA3 has the following I/O port to support the Plug and Play ISA. Address port: 279h Write Data Port: A79h Relocatable Read Data Port: 203h - 03FFh The following four

To switch OPL3-SA3 into configuration mode, there are two methods. First method is to use the normal PnP protocol. After CSN was assigned for all ISA cards by PnP soft- ware, get CSN from CM (configuration manager) and write the CSN to Wake [CSN], then OPL3-SA3 switches into configuration state. Second method is
