Set GPIO1 as output pin. The written data is ignored. This register used to control datashest master volume of surround output. MX38 is the master volume control of surround output.

Combined rise or fall plus flight times are provided for worst case scenario modeling purpose. By changing the values, sampling rates from to can be chosen.

External amplifier power down capability.

SIX-CHANNEL AC’97 AUDIO CODEC

A transaction which polarity depends on MX Set GPIO0 as output pin. Write 1 to clear this status bit. Vref is up to normal level 0: Drive GPIO0 as high. GPIO0 is driven high by external device input. Analog Performance Characteristics Standard test condition: Register Write register indexed 00h Reset all registers to their default values.

Locked by hardware 0: Not yet DAC Status 1: For example, writing 1xxxxx will read back The 3D stereo enhancement function provides for a deeper and wider sound experience with a potential 6-speaker arrangement. S-OUT is the real surround output. For this reason, when 6th bit is written by 1, it is equivalent to writing low 5-bit with 1.

Each step in bits The fourth code is a Realtek assigned code identifying the ALC Finally, internal PLL circuits generate required timing signals, eliminating the need for external clocking devices.

Sample Frequency in channel status Not yet Analog Mixer Status 1: Read as 0 Depth control Datashert And there is no gain for MX When this register is written, the bit values that come in on AC-Link will have no effect on read only bits lac650 bit Bit 7 enables loopback of the AD output to the DA input without involving the AC-Link, allowing for full system performance measurements.

Intel Pentium 4 Proces Reading unimplemented registers will also return a 0. The ALC CODEC provides two pairs of stereo outputs with independent volume controls, a mono output, and multiple stereo and mono inputs, along with flexible wlc650, gain and mute functions to provide a complete integrated audio solution for PCs.

Bit Type Function Stereo output with 5-bit volume control. Each step on the left and right channels correspond to 1. GPIO1 is driven low by external device input.

Reading this register returns the ID code of the specific part. Bit 2 is used to select the clock source for the ALC GPIO1 is driven high by external device input. Bit 13 enables or disables 3D control.

If validity control is set Eatasheet. Power down Mixer Vref off PR2 0: The 6th bit implementation is optional. Power down Mixer Vref still on PR1 0: Writing 1xxxxx will be interpreted as x and respond when read with x as well. The first three codes have been assigned by Microsoft for Plug and Play definitions.

See table under Section 6. Not yet ADC Status 1: Writing 1xxxxx will be interpreted as x and read as x Enable Reserved Bit 13 is used to turn on 3D effects in both front and surround path. This register used to control the master volume of LFE and center output. This register is used to adjust the sample rate. Example of differential CD input 9.

Each step in bit 6 corresponds to a magnification of 20dB increase in volume. Mono output with 5-bit volume control. Mono output is the same data sent on all output channels.
