• Manufacturer Part Number: WM9714L_06
• Description: AC 97 Audio CODEC
• Manufacturer: WOLFSON [Wolfson Microelectronics plc]

3Ch
* “0” corresponds to “ON”, if and only if the corresponding bit in register 26h is also 0.
3Eh
* “0” corresponds to “ON”, if and only if the corresponding bit in register 26h is also 0.
40h
Pre-Production
Register 3Ch is for power management additional to the AC’97 specification. Note that the actual state of each circuit
block depends on both register 3Ch AND register 26h.
Register 3Eh is for power management additional to the AC’97 specification. Note that the actual state of each circuit
block depends on both register 3Eh AND register 26h.
Register 40h is a “general purpose” register as defined by the AC’97 specification. Only two bits are implemented in the
WM9714L.
