I
An I
and modes of the picture processor. Via this interface up to four registers can be written according
to the following transfer protocol for controlling the operation mode:
S: Start condition
A: Acknowledge
P: Stop condition
Slave address: 0 0 1 0 1 0 1
(Note: There is a general description of the I
After every data byte that is transmitted the internal register address (subaddress) is automatically
incremented to the next register so that, if necessary, several registers can be loaded with one I
Bus telegram.
In the multi-picture mode the operating mode transmitted on the I
vertical blanking interval, i.e. during the high phase of signal VS1, if the Memory Sync Controller
(MSC) activates the DREQ line during this period.
It should be noted that the new operating mode has always to be transmitted to the picture
processor first and immediately afterwards to the MSC on the I
30 ms.
This is the only way to ensure interference-free synchronization of the picture processor and the
MSC. The four I
right-hand margin are set by an internally generated reset signal (default values) when the
operating voltage is applied.
