TDA8754
Triple 8-bit video ADC up to 270 Msample/s
8.9 3-level
When the synchronization pulse of the input of the SOG is 3-level, the system will be able
to detect that a 3-level sync is present and will advise the customer if a change is
observed by setting bit HPDO = 1 and pin HPDO = HIGH. It is possible to disable this
function with bit FTRILEVEL. When this automatic function is disabled, the manual mode
will only inuence the separator circuitry.

Description
S
master starts with a start condition
Byte 1
master transmits device address (7 bits) plus write command bit (R/W=0)
A
slave generates an acknowledge
Byte 2
master transmits programming mode and register subaddress to write to
A
slave generates an acknowledge
Byte 3
master transmits data 1
A
slave generates an acknowledge
P
master generates a stop condition
