2. Room Monitoring:
A. System initialization [set MIC gain (REG2 bit(3~0)), set ALC gain 0/+6dB (REG5 bit(1)), set LIN-DRV
gain (REG1 bit(3~0)), set REG3 bit(6,5) and set REG6 bit(1,0)]
B. Switches path:
a. Remote Monitoring:
MIC ⇒ SWA ⇒ PRE-PGA ⇒ SWC (ALC on) ⇒ SWJ ⇒ LIN-DRV ⇒ LOUTP/N
b. Local Detecting DTMF:
LIN ⇒ SWI ⇒ AD1-PGA ⇒ PCM CODEC AIN1
3. Digital Speakerphone:
A. System Initialization [set MIC gain (REG2 bit(3~0)), set AD1-PGA gain (REG6 bit(1,0)), fix the value of
L.P.F., set DA-PGA gain (REG6 bit(3,2)), set ATT1 gain (REG3 bit(3~0)), set LIN
gain (REG1 bit(7~4)), set SWM REG4 bit(4), set LIN-DRV gain (REG1 bit(3~0))]
B. Switches path : set REG0 = 0X00AF
a. CODEC 1 : Record signal from MIC and Play signal to SPKP/N (use digital volume control)
MIC ⇒ SWA ⇒ PRE-PGA ⇒ SWC (ALC off) ⇒ SWD ⇒ AD1-PGA ⇒ PCM CODEC AIN1
PCM CODEC AOUT1 ⇒ L.P.F. ⇒ SWF ⇒ SWG (ATT1) ⇒ SPK-DRV ⇒ SPKP/N
b. CODEC 2 : Record signal from LIN and Play signal to LOUTP/N
LIN ⇒ SWM ⇒ AD2-PGA ⇒ PCM CODEC AIN2
PCM CODEC AOUT2 ⇒ SWE ⇒ LIN-DRV ⇒ LOUTP/N
