For this reason, when 6th bit is written by 1, it is equivalent to writing low 5-bit with 1. Set GPIO1 as output pin.
Bit 9 allows selection of mono output. Set GPIO1 as input pin. Example of differential CD input 9.
Analog Performance Aoc650 Standard test condition: Bit Type Function 15 Reserved GPIO0 is driven high by external device input. The first three codes have been assigned by Microsoft for Plug and Play definitions. Bit Type Function Sample Frequency in channel status Mono output with 5-bit volume control. Note that the 3D bit in the general purpose register bit 13 must be set to 1 to enable this function.
Finally, internal PLL circuits generate required timing signals, eliminating the need for external clocking devices. Bit 8 controls the mic selector. Reading this register returns the ID code of the specific part.
This register used to control the master volume of LFE and center output. See table under Section 6. Bit 13 enables or disables ddatasheet control.
Writing 1xxxxx will be interpreted as x and respond when read with x as well. Always read as 0.
MX38 is the master volume control of surround output. S-OUT is the real surround output. Bit 7 enables loopback of the AD output to the DA input without involving the AC-Link, allowing for full system performance measurements. For example, writing 1xxxxx will read back By changing the values, sampling rates from to can be chosen.
Not yet ADC Status 1: Each step in bit 6 corresponds to a magnification of datashret increase in volume. Low to high transition default 1: The 3D stereo enhancement function provides for a deeper and wider sound experience with a potential 6-speaker arrangement.
Because software modem applications may not have a speaker, the CODEC can offer a speaker-out service.
Bit 2 is used to select the clock source for the ALC Intel Pentium 4 Proces EAPD output low enable external amplifier 1: The ALC will return datasheft uninstalled bits or registers with 0 for the read operation. GPIO0 is driven low by external device input. Each step on the left and right channels dataaheet to 1. Locked R Ca [1: And there is no gain for MX If validity control is set MX3A.
