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

(9) CR9
B7–B0 : Registers for setting the low-order data of the internal data memory.
*1: Although the initial value of CR9 is 00h, it is automatically set to xxh (dependent on DSP firmware version)
before starting the initial mode. By reading the value of CR9 before starting the initial mode, the DSP firmware
version can be checked.
(10) CR10
B7 : CH1 front-end interface selection register
B6 : CH0 front-end interface selection register
B5–B3 : Reserved bits. Do not change the initial values.
B2 : VFRO1 selection register
B1 : VFRO0 selection register
B0 : Reserved bits. Do not change the initial values.

0 : Analog interface
1 : PCM interface
0 : Analog interface
1 : PCM interface
Note:
This code does not allow selecting of an analog interface as a front end interface; therefore, be sure to set
CH1_IFSEL = 1 and CH0_IFSEL = 1 while in the initial mode.
0 : AVREF (Outputs approx. 1.4 V.)
1 : Voice output on the receiving side
0 : AVREF (Outputs approx. 1.4 V.)
1 : Voice output on the receiving side
Note:
This code does not allow selecting of an analog interface as a front end interface; therefore, do not change the
initial values of VFRO0_SEL and VFRO1_SEL.
