Description
Selects I²C Address. Low(0) sets the slave
address to 28h for WRITE and 29h for
READ. HIGH(1) sets the slave address to 2Ah
for WRITE and 2Bh for READ.
Selects the source of the horizontal frequency
signal. Tying pin 2 HIGH(1) selects XIN mode.
Tying pin 2 Low(0) selects HIN mode.
When operating in XIN mode this pin is the
output pin for the XTAL circuit. In HIN mode,
the X_OUT pin is a no connect (NC).
Capable of being tied to an RESET signal if a
Power-On Reset action is required. RESET
must be held Low(0) for at least 100ns;
otherwise, the pin must be tied HIGH(1).
