• Description: 4ch Voip Codec
• Manufacturer: Oki Semiconductor

C. Internal data memory for EC0 GLPAD control (EC0_GLPAD_CR)
B15–B4: Reserved bits. Do not change the initial values.
B3, B2: Output level control
B1, B0: Input level control
D. Internal data memory for controlling EC0 Comfort Noise generation function (EC0_CN_CONT)
OKI Semiconductor
These bits control the GPAD level for the echo canceller output gain.
These bits control the LPAD level for the echo canceller input loss.
Initial value: 000Fh
This data memory controls the GLPAD within the echo canceller 0.
Initial value: 0003h (Comfort Noise generation function enabled)
By writing 0000h to this internal data memory, the comfort noise generation function of EC0 will be disabled.
If center clip control and attenuator control are enabled, write 0003h to this internal data memory in order to
enable the comfort noise generation function. On the other hand, if center clip control and attenuator control are
disabled, write 0000h to this internal data memory in order to disable the comfort noise generation function.
The initial values of both center clip control and attenuator control are set to disable. If center clip control and
attenuator control will not be used, write 0000h to this internal data memory.
