Description
This pin, along with OSC2, is the 2-terminal crystal interface when
using a 2-terminal crystal as the clock input. If an external
oscillator is used as a clock source, then this pin is the clock input.
This pin, along with OSC1, is the 2-terminal crystal interface when
using a 2-terminal crystal as the clock input. If an external
oscillator is used as a clock source this pin should be left
unconnected.
Panel display data bus. The data format depends on the
specific panel connected. For 4-bit single panels, LD3-LD0
are driven low (0 state).
Display data shift clock. Data is shifted into the LCD
X-drivers on the falling edge of this signal.
Display data latch clock. The falling edge of this signal is
used to latch a row of display data in the LCD X-drivers
and to turn on the Y driver (row driver).
For format 1 of 8-bit single color panels this is the second
shift clock.
For all other modes, this is the LCD backplane BIAS
signal. This output toggles once every frame, or as
programmed in AUX[05] bits 7-2.
Vertical scanning start pulse. A logic ‘1’ on this signal,
sampled by the LCD module on the falling edge of LP, is
used by the panel Y driver (row driver) to indicate the start
of the vertical frame.
LCD enable signal output. It can be used externally to turn
off the panel supply voltage and backlight.
