MACROVISION
When enabled, the Luma and Chroma signals are modified according to the MACROVISION
protection process for Pay Per View (PPV) applications revision 7.01 dated Sep 6th , 1996.
Enabling and control is through the serial control bus.
No parts will be sent to the customer until the customer provides MOTOROLA with written confirmation of
a license, non-disclosure or waiver from MACROVISION
If your customer would NOT like to use this feature or customer do NOT have an agreement of the copy
protection with MACROVISION, and then you should recommend the MC44723FT (no copy guard part).
Serial Control Bus
Control of the DVE device is accomplished through the I2C-Bus or SPI serial bus.
In I2C mode, pins SDA and SCL are the respective data and clock signals. Device address can be
40(hex)/41(hex) or 1E(hex)/1F(hex) . Slave address is chosen at reset by the state of the ChipA pin
signal { 0 : 40(hex)/41(hex), 1 : 1E(hex)/1F(hex) }
Sub-address register read and write operations are documented in the following section.
In SPI mode, pins SO, SI, SCK and SEL are the respective data input, output, serial clock and chip
select signals. Register read and write operations are documented in the following section.
