• Manufacturer Part Number: ak4560a
• Description: 16bit Codec With Alc And Mic/hp/spk-amps
• Manufacturer: AKM Semiconductor, Inc.

ASAHI KASEI
Operation Mode
MS0028-E-00
Addr Register Name
07H
* When FADEIN or FADEOUT operation is done, ALC1 bit should always be “1”.
ALC1: ALC1 Enable Flag
FDOUT: FADEOUT Enable Flag
FDIN: FADEIN Enable Flag
ALC2: ALC2 Enable Flag
ND: REF6-0 value of ALC1 is decreased to –3.5dB.
STAT: Status Flag
Operation Mode
RESET
R/W
0: Disable (RESET)
1: Enable
0: Disable (RESET)
1: Enable
0: Disable (RESET)
1: Enable
0: Disable
1: Enable (RESET)
After initializing cycle (2048/fs=42.7ms@fs=48kHz), ALC2 is enabled. This initializing cycle
starts when PD pin change “L” to “H” or SPKP bit change from “0” to “1”.
0: Keep REF6-0 value of ALC1 (RESET)
1: Decrease –3.5dB from REF6-0 value of ALC1
This bit and ND pin are ORed.
When this function is controlled by ND pin, ND bit is fixed to “0”. When this function is
controlled by ND bit, ND pin is fixed to “L”.
0: In case of ALC1 (including FADEIN, FADEOUT and Noise Decreasing function) operation
or initializing cycle. (RESET)
1: Manual Mode
STAT bit is “0” during initilizing operation after exiting power-down by PD pin. After the
finish of the initilizing operation, STAT bit becomes “1”.
During the ALC1 operation, STAT bit becomes “1” after the max “1” ATT/GAIN operation is
completed by internal state.
