PE.
In the initial state, (1) is selected. This setting is switched by commands.
8
CDLR
Background color phase
Connection for the resistor used to adjust the background color phase
adjustment
Outputs the result of the judgment as to whether or not the external sync signal is present.
9
SYNCJDG
External sync signal judgment A high level is output when a sync signal is present.
/Rout
output (Rout output)
The dot clock (LC oscillator) is output when RST is low.
(The IC can be set up to not output this signal during resets by commands.)
