Figure 97. LCD Module Block Diagram
The LCD Controller can be clocked by an internal synchronous or an external asynchro-
nous clock source. The clock source clk
When the LCDCS bit in the LCDCRB Register is written to logic one, the clock source is
taken from the TOSC1 pin.
The clock source must be stable to obtain accurate LCD timing and hence minimize DC
voltage offset across LCD segments.
The prescaler consist of a 12-bit ripple counter and a 1- to 8-clock divider. The
LCDPS2:0 bits selects clk
If a finer resolution rate is required, the LCDCD2:0 bits can be used to divide the clock
further by 1 to 8.
Output from the clock divider clk
The display memory is available through I/O Registers grouped for each common termi-
nal. When a bit in the display memory is written to one, the corresponding segment is
energized (on), and non-energized when a bit in the display memory is written to zero.
To energize a segment, an absolute voltage above a certain threshold must be applied.
This is done by letting the output voltage on corresponding COM pin and SEG pin have
opposite phase. For display with more than one common, one (1/2 bias) or two (1/3
bias) additional voltage levels must be applied. Otherwise, non-energized segments on
COM0 would be energized for all non-selected common.
