MACROVISION
When enabled, the Luma and Chroma signals are modified according to the MACROVISION
protection process for Pay Per View (PPV) and DVD applications revision 7.01 dated Sep 6th , 1996.
Enabling and control is through the serial control bus.
No MC44724A parts will be sent to the customer until the customer provides MOTOROLA with written
confirmation of a license, non-disclosure or a waiver from MACROVISION
The MC44725A device is available without MACROVISION
Serial Control Bus
Control of the DVE device is accomplished through the I2C-Bus or 4-wired 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 figures 22a - 22b.
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 figures 23a - 23b
