6 / 52 page  Pin Name I/O Description LCD Driver SEG47~SEG0 O or I/O LCD panel segment outputs. Some segment outputs can be optioned to Bidirectional input/output ports by software. (See the ²LCD Driver² function) COM15~COM0 O or I/O LCD panel common outputs. Some common outputs can be optioned to Bidirectional input/output ports by software. (See the ²LCD Driver² function) VLCD I LCD driver power source. Normal I/O PA7~PA0 I/O Bidirectional input/output ports. Schmitt trigger input and CMOS output. See mask option table for pull-high and wake-up function PB7~PB0 I/O Bidirectional input/output ports. Schmitt trigger input and CMOS output. See mask option table for pull-high function PD7~PD0 I/O Bidirectional input/output ports. Schmitt trigger input and CMOS output. See mask option table for pull-high function Port D could be optioned to LCD signal output, see the ²Input/Output Ports² function PE3~PE0 I/O Bidirectional input/output ports. Schmitt trigger input and CMOS output. See mask option table for pull-high function Port E could be optioned to LCD signal output, see the ²Input/Output Ports² function PF7~PF0 I/O Bidirectional input/output ports. Schmitt trigger input and CMOS output. See mask option table for pull-high function PG3~PG0 I/O Bidirectional input/output ports. Schmitt trigger input and CMOS output. See mask option table for pull-high function Dialer I/O (See the ²Dialer I/O Function²) HFI I Schmitt trigger input structure. An external RC network is recommended for input debouncing. This pin is pulled low with internal resistance of 200k W typ. HFO O CMOS output structure. HDI I Schmitt trigger input structure. An external RC network is recommended for input debouncing. This pin is pulled high with internal resistance of 200k W typ. HDO O CMOS output structure. HKS I This pin detects the status of the hook-switch and its combination with HFI/HDI can con- trol the PO pin output to make or break the line. PO O CMOS output structure controlled by HKS and HFI/HDI pins and which determines whether the dialer connects or disconnects the telephone line. DNPO O NMOS output structure. XMUTE O NMOS output structure. Usually, XMUTE is used to mute the speech circuit when trans- mitting the dialer signal. Peripherals DTMF O This pin outputs dual tone signals to dial out the phone number. The load resistor should not be less than 5k W. MUSIC O This pin outputs the single tone that is generated by the PFD generator. LBIN I This pin detects battery low through external R1/R2 to determine threshold voltage.
