In idle state (HKS is “High” and HFO is “Low”), these pins stay “High impedance” level to prevent power consumption. Otherwise, these pins switch to “High” level for detecting keyboard entry. These pins will output 600 Hz signal while keyboard is scanning. Keyboard scan pins of column group. In idle state, these pins stay “High impedance” level. Otherwise these pins switch to “Low” level for detecting keyboard entry. These pins will output 600 Hz signal while keyboard is scanning. The fourth column group pin of the keyboard that also provides the keytone output . Normally, this pin stays “Low” level for detecting keyboard entry. After a valid keyboard entry, this pin will output keying confirmation tone that is 600 Hz signal and 30 ms duration. While DTMF output, the key tone will be disabled. To prevent signal interference, while DTMF issue, it will disable key tone output except function key. Oscillator input and output pins. A 3.579545 MHz crystal or ceramic resonator must be crossed connection to XIN and XOUT pins which generate system clock. The Tone/Pulse MUTE signal output pin that is NMOS open-drain output structure. This pin will switch to “Low” level during Tone/Pulse dialing. Otherwise, this pin stays “High impedance” level. Positive and negative power supply input pins. Recommended operating voltage from 2.0Vdc to 5.5Vdc. Handfree inputs pin which accepts falling edge signal to turn “on” or turn “off” handfree function. This pin is hysteresis input structure and built-in pull up resistor (typically 200 Kohms). Handfree outputs pin that is designed to control telephone line for on-hook dialing or control speakerphone circuit for handfree conversation. When handfree function is executed, this pin will switch to“High”. Otherwise, this pin stays “Low” level. The DTMF (Dual Tone Multi-Frequency) output pin. Normally, this pin stays“Low” level. In Tone dialing mode, this pin will output DTMF signal that is corresponding to keyboard 0..9, * and # keys. Control signal inputs pin that is corresponding hook switch status. When handset was left from cradle, this pin must be connected to “Low” level to operate all functions. Otherwise, this pin must be connected to “High” level to disable all function and prevent power consumption. Pulse signal outputs pin that is NMOS open-drain output structure. Normally, this pin stays “High impedance” level. In Pulse dialing mode and keypad was entry. This pin will output pulse trains signal that is corresponding to keyboard 0 .. 9 keys. Pulse signal outputs pin that is CMOS inverter output structure. Normally, this pin stays “Low” level. During pulse signal dialing or flash function executing, this pin will switch to “High” level to control the external circuit. SDO function output that is NMOS open-drain structure. When there is a valid entry on keyboard, this pin will output a serial data. This serial data is designed to drive LCD driver to display dialing number on LCD screen or drive voice synthesizer to announce dialing number to speaker. * This specification are subject to be changed without notice. 10.1.1997 3 EM91215 SERIES TONE/PULSE SWITCHABLE DIALER WITH LCD INTERFACE FUNCTION DESCRIPTIONS Dialing signal selection The EM91215 series incorporated a special keyboard scanning function that is connecting a resistor (typically is 560 Kohms) on keyboard scan pin to select many telephone specifications.

Operating procedure described as follow : • To select Pulse or Tone mode. • Off-hook or turn on HF function. • Keying d1, d2, .. , dn. The “d” expressed digital keypad that included 1~9, *, 0, #, P, and P→T keys. The “n” expressed unlimited. • The numbers d1, d2, .. , dn will be dialed out in Pulse or Tone mode as selection. LNB redial memory Storing: In normal dialing mode, every digital key was entry which number will be stored in LNB memory automatically. If entry digits are more than 32 digits, the redial function of LNB memory will be disabled. Otherwise, these numbers stored in LNB memory can be redial output. Redialing: After normal dialing, directly keying F key (or On-Off hook once) and keying RD key on keyboard. The numbers that are stored into LNB memory will be dialed output. * This specification are subject to be changed without notice. 10.1.1997 4 EM91215 SERIES TONE/PULSE SWITCHABLE DIALER WITH LCD INTERFACE SAVE redial memory The SAVE meomry is designed in EM91215 series to support 32 digits capacity buffer for second redial, pager, Memory and other system applications. Storing : EM91215 series support two operating methods to store numbers into SAVE redial memory. Method 1 • To select Pulse or Tone mode. • Off-hook (or turn on HF function), push d1, d2, .. , dn. The numbers d1, d2, .. , dn will be dialed out in Pulse or Tone mode as selection. • After dn had been dialed out and push [ST], Save key. If the keying numbers are more than 32 digits that content of SAVE memory can not be updated. Otherwise, these numbers will be stored into SAVE memory. In the [] key allows to be omitted. Method 2 Off-hook (or turn on HF function), push ST, d1, d2, .. , dn, [ST], Save. If the keying numbers are not over 32 digits, the numbers d1, d2, .. , dn will be stored in SAVE redial memory automatically. Dialing : • To select Pulse or Tone mode. • Off-hook (or turn on HF function), push Save key. The numbers stored in SAVE memory will be dialed out in Pulse or Tone mode as selection. Repertory memory The EM91215 series incorporated several sets repertory memory and each one can store number up to 16 digits. These memories were designed to 13 sets types. As operating precedure, all of the memories can be separated to dirtect (one-touch) and indirect (two-touch ) operation. In memory storing, if stored numbers are more than 16 digits that only the previous 16 digits can be stored into specific memory. Otherwise, these numbers can be stored entirely. After memory dialed out, the content of LNB is keeping to current data. Storing of 13 sets memory types Direct (one-touch) operation Off-hook (or turn on HF function), push ST, d1, d2, .. , dn [ST], EMn or M1~M10 (ROW5 optioned).
