The slave address consists of 7 bits of address along with 1 bit of read/write information as shown in

Figures 2–4 and 2–5. For the TVP6000, the possible slave addresses (including the read/write bit) are 0x40

or 0x42 for write cycles or 0x41 and 0x43. Refer to Table 2–7 for additional base address information.

Data Manager

The data manager resides at the very beginning of the processing pipeline. It receives the Y Cb Cr pixel data

from the pixel bus and converts it to its internal YUV representation. Register F_CONTROL at subaddress

3A and the SCN bit of the SCM register at subaddress 90 define the function of the data manager.

The data manager can receive data on either an 8-bit or 16-bit video port. In the 8-bit format, it receives data

at port VP1 or VP2 (both 8-bits wide) depending on register bit FMT2, at every rising edge of LLC if scan

conversion is disabled, and at every (rising and falling) edge of LLC if scan conversion is enabled. In the

16-bit format, it receives luminance information on the VP1 port and chrominance information on the VP2

port, at alternate rising edges of LLC (qualified by CREF) if scan conversion is disabled, or at every rising

edge of LLC if scan conversion is enabled. Additionally, the data manager can generate pixels internally for

a 100/100 color bar if the CBAR bit is set. The Y, U, and V values for this color bar are shown in Table 2–3.
