YMF754
DS-1E
Preliminary
OVERVIEW
YMF754 (DS-1E) is a high performance audio controller for the PCI Bus. DS-1E consists of two separated
functional blocks. One is the PCI Audio block and the other is the Legacy Audio block.
PCI Audio block provides 64-voice XG wavetable synthesizer with reverb and variation by using the software
driver from YAMAHA. It also supports DirectSound hardware accelerator, Downloadable Sound (DLS) and
DirectMusic accelerator.
Legacy Audio block supports FM synthesizer, Sound Blaster Pro, MPU401 UART mode and Joystick function
in order to provide hardware compatibility for numerous PC games on real DOS without any software driver.
DS-1E supports the connection to AC’97 which provides high quality DAC, ADC and analog mixer, and it can
connect two AC’97s. In addition, it supports consumer IEC958, Digital Audio Interface (SPDIF In/Out), to
connect external audio equipment by digital.
In addition to support the same functions of YMF744B (DS-1S), DS-1E adds direct recording function for
SPDIF In, and realizes to use SPDIF In and Zoomed Video Port at the same time. And, DS-1E is featured
with the capability of dramatically reducing power consumption at normal operation.

2C-2Dh: Subsystem Vendor ID
Read Only
Default: 1073h
Access Bus Width: 8, 16, 32-bit
b15 b14 b13 b12 b11 b10 b9 b8 b7 b6 b5 b4 b3 b2 b1 b0
Subsystem Vendor ID
b[15:0] ........Subsystem Vendor ID
This register contains the Subsystem Vendor ID. In general, this ID is used to distinguish adapters or
systems made by different IHVs using the same chip by the same vendor. This register is read only. To
write the IHV’s Vendor ID, use 44-45h (Subsystem Vendor ID Write Register). IHVs must change this
ID to their Vendor ID in the BIOS POST routine.
In case of the system such as Sound Card which BIOS can not control, this ID can be changed by
connecting EEPROM externally. Then, Subsystem Vendor ID Write Register is invalid.
In case EEPROM is not externally, the default value is the YAMAHA's Vendor ID, 1073h.
2E-2Fh: Subsystem ID
Read Only
Default: 0012h
Access Bus Width: 8, 16, 32-bit
b15 b14 b13 b12 b11 b10 b9 b8 b7 b6 b5 b4 b3 b2 b1 b0
Subsystem ID
b[15:0] ........Subsystem ID
This register contains the Subsystem ID. In general, this ID is used to distinguish adapters or systems
made by different IHVs using the same chip by the same vendor. This register is read only. To write
the IHV's Device ID, use 46-47h (Subsystem ID Write Register). IHVs must change this ID to their ID
in the BIOS POST routine.
In case of the system such as Sound Card which BIOS can not control, this ID can be changed by
connecting EEPROM externally. Then, Subsystem ID Write Register is invalid.
In case EEPROM is not externally, the default value is the YAMAHA's Device ID, 0012h.
34h: Capability Register Pointer
Read Only
Default: 50h
Access Bus Width: 8, 16, 32-bit
b7 b6 b5 b4 b3 b2 b1 b0
Capability Register Pointer
b[7:0] ..........Capability Register Pointer
This register indicates the offset address of the Capabilities register in the PCI Configuration register
when 58-59h: ACPI Mode register, ACPI bit is “0”. DS-1E provides PCI Bus Power Management
registers as the capabilities. The Power Management registers are mapped to 50h - 55h in the PCI
Configuration register, and this register indicates “50h”.
When ACPI bit is “1”, this register indicates “00h”.
