Loaded from UV [7:0] pins on powerup reset

Loaded from Y [7:0] pins on powerup reset
This field identifies the subsystem manufacturer(for example, the board manufacturer). Address 005 is the MSB. The
values of this field are set at the device power up or reset by sampling the state of Y[7:0] and UV[7:0] terminals. The
Y[7:0] and UV[7:0] terminals may be tied to pullup or pulldown resisters to determine a fixed value for the subsystem
vendor ID.
The default can be overwritten by writing a different value to the register as the first access to this register after reset.
This register is read-only after the first write or read.

Loaded from A[1:0], VSYN, HSYN, Y[9:8], and UV[9:8] pins on powerup reset.
This field identifies the subsystem device. Address 007 is the MSB. This field is one time writeable, similar to the
Subsystem Vendor ID.

Power state
This register is both readable and writable. When read, this register indicates the current power state of TVP5040.
Bit 0 and bit 1 define four possible power states.
0 0 =
P0 state. Fully on. This is the normal operation mode. (default)
0 1 =
P1 state. Not supported
1 0 =
P2 state. Not supported.
1 1 =
P3. A/D converters are turned off and the internal clock is reduced to minimum. Power may or may not be removed.
Writing to these two bits will force TVP5040 to one of the four power states as defined above.
