AK4650 Datasheet, PDF (68/86 Pages) Asahi Kasei Microsystems – 16Bit ΔΣ CODEC with MIC/HP/SPK-AMP & TSC
[AK4650]
[Slot 2]: Status Data Port
Status data addressed by command address port of Output Stream is output through SDATAIN pin.
Bit 19-4 Control Register Read Data (16bit; the contents of indexed address in the slot 1)
Bit 3-0 “0” (4bit)
Note that the address of Status Data Port data are consistent with Status Address Port data of the slot 1 in the same
frame. If the read operation is issued in the frame N by AC’97 controller, Status Data Port data is output through
SDATAIN in the frame N+1. Note that data is output in only this frame, only one time and that the
following frames are invalid if the next read operation is not issued.
[Slot 3]: PCM Record Left Channel
Record (ADC) data format is MSB first. Data format is 2’s complement. As the resolution of the AK4650 is 16bit, lower
4 bits are ignored. If ADC block is powered down, slot 3 valid bit in the slot 0 is invalid (“0”), and data is output as all “0”.
Bit 19-4: Audio ADC left channel output (16bit)
Bit 3-0: “0” (4bit)
[Slot 4]: Reserved for future enhancement
Bit 19-0 “0”
[Slot 5]: 12bit ADC data for TSC
When SLOT bit = “1” and SLOTNO1-0 bits = “00”, 12bit ADC data is output.
Bit 19: ADE (1bit; “0”=Invalid, “1”=Valid)
Bit 18-16: A2-0 (3bit; Measurement mode)
Bit 15-4: D11-0 (12bit; 12bit ADC data)
Bit 3-0: “0” (4bit)
[Slot 6]: 12bit ADC data for TSC
When SLOT bit = “1” and SLOTNO1-0 bits = “00”, 12bit ADC data is output.
Bit 19: ADE (1bit; “0”=Invalid, “1”=Valid)
Bit 18-16: A2-0 (3bit; Measurement mode)
Bit 15-4: D11-0 (12bit; 12bit ADC data)
Bit 3-0: “0” (4bit)
[Slot 7-11]: Reserved for future enhancement
Bit 19-0 “0”
[Slot 12]: 12bit ADC data for TSC, pen touch and headphone jack detection results
When SLOT bit = “1” and SLOTNO1-0 bits = “10”, 12bit ADC data is output. When SLOT bit = “1”, pen touch and
headphone jack detection results are output regardless of SLOTNO1-0 bits.
Bit 19: ADE (1bit; “0”=Invalid, “1”=Valid)
Bit 18-16: A2-0 (3bit; Measurement mode)
Bit 15-4: D11-0 (12bit; 12bit ADC data)
Bit 3-2: “0” (2bit)
Bit 1: DTHPJ (1bit; “0”=Not inserted, “1”=Inserted)
Bit 0: DTPEN (1bit; “0”=Not touched, “1”=Touched)
