2004.05.04(拳) 捞 夸茄 急烙

SMDK2410 IIS MIC 涝仿 Gain 炼沥 包访 荐沥 搬苞 涝聪促.

1. 窍靛傀绢 矫规 
 - SMDK2410 焊靛 惑俊 MIC1 免仿 窜阑 UDA1341TS IIS 内郸狼 Input Channel Pin 6, 8 (VINL2, VINR2)俊 搬急窃.

2. 家橇飘傀绢 荐沥 
 - Codec input channel 2 Amp狼 Gain阑 炼例窍扁 困茄 内靛 梅啊窃. (盔夯 内靛绰 梅何 曼炼 官而聪促.)

//In case of using Input channel 2 Amp. gain
  _WrL3Addr(0x14 + 0);    //DATA0 (000101xx+00)
  _WrL3Data(0xc2,0);      //1100 0,100  : Extended addr(3bits), 100 
  _WrL3Data(0xe3,0);      //111,000,11 : DATA0, Disable AGC for MIC Amp. Gain Control 

  _WrL3Addr(0x14 + 0);    //DATA0 (000101xx+00)
  _WrL3Data(0xc5,0);      //1100 0,101  : Extended addr(3bits), 101 
  _WrL3Data(0xff,0);      //111,111,11 : DATA0, Input channel 2 Amp => Max. 60.5dB, input channel 2 select  

  => IG[6:0] 蔼阑 技泼窍咯 input channel 2 Amp狼 Gain阑 炼例 啊瓷窃. (惑技 郴侩 IIS 内郸 单捞鸥 矫飘 曼炼 夸噶)

3. 角氰 搬苞
 - IG[6:0] 蔼阑 啊函窍哥 MIC 踌澜 饶 犁积窍咯 涝仿 Gain 啊函 犬牢窃.
 - Gain阑 刘啊 矫糯俊 蝶扼 (弥措 60.5dB) 林函狼 累篮 家澜档 MIC 踌澜 饶 没秒 啊瓷窃.
