Table 0-3 Clock Input Pins
Description
Vertical Scanning Start Pulse output. A logic 1 on this signal, sampled
by the LCD module on the falling edge of LP, is used by the panel row
drivers (Y drivers) to indicate the start of the vertical frame.
Latch Pulse output. The falling edge of this signal is used to latch a
row of display data in the LCD module’s column driver shift registers
and to turn on the row driver (Y driver) for that line.
Shift Clock for LCD data. Display data is clocked out of the chip on the
rising edge of this signal, to be shifted into the LCD panel module
column drivers (X drivers) on each falling edge.
Description
This pin, along with CLKO1 is the 25.175 MHz 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 CLKI1 is the 25.175 MHz2-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 should be
left unconnected.
This pin, along with CLKO2 is the 28.322 MHz 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 CLKI2 is the 28.322 MHz 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 should be
left unconnected.
