10. TERMINAL FUNCTION
1. SCL
SCLterminal isaserial lock input terminal and used for TX/RX
control between master and slave.
2. SDA
SDA terminal isan input/output terminal and transfers the
address sent from the master device to slave and mutual data.
SDA output circuitemploysthe open drain, therefore the pull-up
resistor isrequ Terminal ired.
3. A0, A1, A2
The terminalsof A0, A1and A2are not used.
4. WP
The WP terminal controlswriting operation. Reading onlyis
allowed when WP ishigh, and both reading and writing are
allowed when WP islow.
11. CIRCUIT OPERATION
11.1. Bell Detector Circuit
17

Whenthe bell signal is input betweenT/R, the signal is outputtedat the speakervia the
following path:
Tel line R1/C1 Pin1 of IC2/Pin8 of IC2 Pin5 of IC2 PC1 SW1 Ringer
11.2. Line Interface
Intalk mode, SW101 becomes ON and Q104 base becomes High, causing Q104 and Q102 toturn
on and line loop is established.
The loop current flows as follows: D101(+) Q102 Q108 R114 D103.
The pulse signal that switches ON/OFF is output frompin39 of the CPU.
Q104 and Q102 switchthe line loop ON/OFF, generating the dial pulse signal.
11.3. Telephone Line Interface
11.3.1. Circuit operation
-Onhook
Q102 cuts the DC loop current and the voice signal.
-Off hook
Q102 turns on to go into off-hook condition and the following
signal flow isfor the DC loop current.
TD101 Q102 Q108 R114 D103 D101 R
-The receiving signal flows:
TEL line Q102 C105 C401 R401 Q401 Q403 Q404

11.4. Initializing Circuit
11.4.1. Function:
This circuit is usedtoinitialize the CPU whenthe batteries are installed.
11.4.2. Circuit operation:
Whenthe batteries are insertedintothe unit, the voltage is regulatedbyIC302 and poweris
suppliedtothe CPU.
The unit starts operating soon afterthe voltage goes beyond the point A inthe voltage diagram.

11.5. Caller IDDetect Circuit
11.5.1. Function (FSK signal)
The callerID is a chargeable ID that the userof telephone circuit obtains byentering a contract
withthe telephone companytoutilize a callerID service. Forthis reason, the operation of this
circuit assumes that a callerID service contract has beenenteredforthe circuit being used. The
data forthe callerID fromthe telephone exchange is sent during the interval betweenthe first
and second rings of the bell signal.
The data fromthe telephone exchange is modemsignal and modulatedinFSK (FrequencyShift
Keying) format. Data 0 is 1200Hz sine wave, and data 1 is 2200Hz sine wave. There are twotypes
of message format: the single message format and plural message format. The plural message
format allows transmitting the name and data code information inaddition tothe time and
telephone numberdata.
