When on-hook (HKS=high) all the pins are set high. While off-hook the column group (C1~C8) remains low and the row group (R1~R5) is set high for key input detection. An inexpensive single contact 5´8 keyboard can be used as an input device. Pressing a key connects a single column to a single row, and actuates the system oscillator that results in a dialing signal output. If more than two keys are pressed at the same time, no response occurs. The key-in debounce time is 20ms. Refer to the keyboard information for keyboard arrangement and to the functional description for dialing specification selection. The system oscillator consists of an inverter, a bias resistor and the necessary load capacitor on chip. Connecting a standard 3.579545MHz crystal or ceramic resonator to the X1 and OSCILLATOR X2 terminals can implement the oscillator function. The oscillator is turned off in the standby mode, and is actuated whenever a keyboard entry is detected. NMOS OUT XMUTE is an NMOS open drain structure pulled to VSS during dialing signal transmission. Otherwise, it is an open circuit. XMUTE is used to mute the speech circuit when transmitting the dial signal. CMOS IN This pin is used to monitor the status of the hook-switch and its combination with HFI can control the PO pin output to make or break the line. HKS=VDD: On-hook state (PO=low). Except for HFI/HDI (hand-free/hold-line control input), other functions are all disabled. HKS=VSS: Off-hook state (PO=high). The chip is in the standby mode and ready to receive the key input. CMOS OUT This pin is a CMOS output structure which by receiving the HKS and HFO signals, control the dialer to connect or disconnect the telephone line. PO outputs a low to break the line when HKS is high (on-hook) and HFO is low (hand-free inactive). PO outputs a high to make the line when HKS is low (off-hook) or HFO is high or HDO is high. During the off-hook state, this pin also outputs the dialing pulse train in pulse mode dialing. While in the tone mode, this pin is always high. 4 January 12, 2000 HT9320F Pin Name MODE DTMF HDI HDO HFI HFO DOUT I/O I/O O I O I O O Internal Connection Description CMOS IN/OUT This is a three-state input/output pin, used for dialing mode selection, either Tone mode or Pulse mode, 10pps/20pps MODE=VDD: Pulse mode, 10pps MODE=OPEN: Pulse mode, 20pps MODE=VSS: Tone mode During pulse mode dialing, switching this pin to the tone mode changes the subsequent digit entry to tone mode. When the chips are in tone mode, switching to pulse mode will also be recognized. CMOS OUT This pin is active only when the chip transmits tone dialing signals. Otherwise, it always outputs a low. The pin outputs tone signals to drive the external transmitter amplifier circuit. The load resistor should not be less than 5kW. CMOS IN Pull-high This pin is a schmitt trigger input structure. Active low. Applying a negative going pulse to this pin can toggle the HDO output once. An external RC network is recommended for input debouncing. The pull-high resistance is 200kW typ. CMOS OUT The HDO is a CMOS output structure. Its output is togglecontrolled by a negative transition on HDI. When HDO is toggled high, PO keeps high to hold the line. The hold function can be released by setting HFO high or by an on-off hook operation or by another HDI input. The HDO pin can directly drive the HT3810 series melody generator to produce a hold-line background melody. Refer to the functional description for the hold-line function section. CMOS IN Pull-low This pin is a schmitt trigger input structure. Active high. Applying a positive going pulse to HFI can toggle the HFO once and hence control the hand-free function. The pull-low resistance of HFI is 200kW typ. An external RC network is recommended for input debouncing. CMOS OUT The HFO is a CMOS output structure. Its output is togglecontrolled by a positive transition on HFI pin. When HFO is high, the hand-free function is enabled and PO outputs a high to connect the line. The hand-free function can be released by an on-off-hook operation or by another HFI input or by setting HDO high. Refer to the functional description for the hand-free function operation. NMOS OUT NMOS open drain output pin. It outputs the BCD code of the dialing digits to the LCD driver chip (HT16XX series) or to the mC for dialing number display. Refer to the functional description for the detailed timing. 5 January 12, 2000 HT9320F I/O Internal Connection Description CLOCK O NMOS OUT NMOS open drain output. When dialing, it outputs a series of pulse trains for DOUT data synchronization. DOUT data is valid at the falling edge of the clock.
