39 / 112 page  12.0 Status & Control Registers (Continued) 12.18 SIDETONE ATTENUATION REGISTER This register is used to control the analog sidetone attenuation. (Note 20) TABLE 19. SIDETONE (0x0Dh) Bits Field Description 3:0 SIDETONE_ ATTEN Programs the attenuation applied to the microphone preamp output to produce a sidetone signal. SIDETONE_ATTEN Attenuation 0000 2 -Inf 0001 2 −30 dB 0010 2 −27 dB 0011 2 −24 dB 0100 2 −21 dB 0101 2 to 10102 −18 dB to −3 dB 1011 2 to 11112 0dB Note 20: An active SIDETONE path to an audio output may result in the microphone DC blocking caps causing audio pops under the following situations: 1) Switching between internal and external microphone operation while in chip modes ’10’ or ’11’. 2) Toggling in and out of powerdown/standby modes. 3) Toggling between chip modes ’10’ and ’11’ whenever external microphone operation is selected. 4) The insertion/removal of a headset while in chip modes ’10’ or ’11’ whenever external microphone operation is selected. To avoid potential pop noises, it is recommended to set SIDETONE_ATTEN to ’0000’ until DC points have stabilized whenever the SIDETONE path is used. www.national.com 39 |
