Some segment outputs can be optioned to Bidirectional input/output ports by software.
(See the LCD Driver 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 LCD Driver 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 Input/Output Ports 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 Input/Output Ports 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 Dialer I/O function )
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
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
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.
