Signal Descriptions
INTn
Interrupt
The DTTV receiver asserts INTn when an internal,
unmasked interrupt flag is set. INTn remains asserted as
long as the interrupt condition persists and the interrupt
flag is not masked. When not driven, the line is open-
drain 3-stated.
O
P_S
Microprocessor Operation Mode
When this signal is LOW, operation is Parallel Mode;
when HIGH, operation is Serial Mode.
I
READ
Read Strobe
When HIGH, a read operation is selected; when LOW, a
write operation is selected. In Serial interface mode,
READ must be connected to VDD.
I
5.3 Main Signals
This section lists and describes the main signals input to the L64780 or
output to the L64705/L64724.
ADCGVDD
Guard VDD for Internal ADC
Must be connected to VDD.
I
ADCGVSS
Internal ADC Guard VSS
Must be connected to ground.
I
ADCPD
Power-Down Mode for Internal ADC
This pin is active HIGH and in normal mode must be con-
nected to ground.
I
ADCVDD
Analog VDD for Internal ADC
Must be connected to VDD.
I
ADCVREFN
Internal ADC Negative Reference Voltage
When not used, this pin must be connected to ground.
I
ADCVREFP
Internal ADC Positive Reference Voltage
When not used, this pin must be connected to ground.
I
ADCVSS
Analog VSS for Internal ADC
Must be connected to ground.
I
AVIN
Analog Input for Internal ADC
For an external ADC, this pin must be connected to
ground.
