16. LCD Controller/Driver
The LCD controller/driver can drive an LCD (Liquid Crystal Display) directly.
The LCD is driven by 4 common outputs and 32 segment outputs.
The output mode can be set to 1/2, 1/3, or 1/4 duty.
LCD controller/driver functions
Bias, duty, and common output combinations
Function
Divider resistor for LCD
drive power
Either the internal resistor (approx. 100 k
) or an externally connected resistor can
be selected.
Common outputs
Max 4 outputs (The corresponding pins cannot be used as I/O ports when using an
LCD.)
Segment outputs
Max 32 outputs (of these, 24 pins can be used as I/O ports in blocks of 8 pins.)
Display data memory
16 bytes of RAM for internal display are provided
Duty
1/2, 1/3, or 1/4 can be selected.
Bias
1/3 only supported
Drive clock
Either the oscillation clock (HCLK) or sub-clock (SCLK) can be used.
Interrupts
None
EI2OS support
Not supported by the extended intelligent I/O service (EI2OS) .
