Description
Output pin of signals to control off-hook and dial pulses. (*1)
“0” : On-hook or break state of dial pulse, “1” : Off-hook or make state of dial pulse
When PDN/RST = “0”, this pin outputs “0”.
Output pin of signals to control a connection to a parallelly connected telephone. (*1)
“0” : phone line is connected to the parallelly connected phone
“1” : phone line is connected to the modem (the parallelly connected phone is disconnected from
the phone line)
When PDN/RST = “0”, this pin outputs “0”.
Call-in state input pin. (*2)
Input “0” when call-in is detected.
Input “1” when call-in is not detected.
When a ring detect circuit is not used, input “1”.
Output for speaker control signal
“0” : speaker On , “1”: speaker Off
When PDN/RST = “0”, this pin outputs “1”.
