XBP

Extended color back porch 2 MSBs. These two bits hold the MSBs of a 10-bit

value extending from 0 to 1023 PCK cycles. The LSBs are located in control

5-4

Active video 2 MSB. These two bits hold the MSBs of a 10-bit value extending

from 0 to 1023 PCK cycles. The LSBs are located in control register 15.

3-2

Active video start 2 MSBs. These two bits hold the MSBs of a 10-bit value which

is the initial half active video length extending from 0 to 1023 PCK cycles. The

LSBs are located in control register 16.

1-0

Active video end 2 MSBs. These two bits hold the MSBs of a 10-bit value which

is the end half active video length extending from 0 to 1023 PCK cycles. The

LSBs are located in control register 17.

7-0

Front porch length. This 8-bit register holds a value extending from 0 to 255

PCK cycles.

7-0

Equalization pulse LOW length. This 8-bit register holds a value from 0 to 255

PCK cycles.

7-0

Equalization pulse HIGH length. This 8-bit register holds a value extending from

0 to 255 PCK cycles. This value, when added to 256 (or 512), determines the

final pulse length in the range of 256 to 511 (or 767) PCK cycles.

7-0

Vertical sync LOW length. This 8-bit register holds a value from 0 to 255 PCK

cycles. This value, when added to 256 (or 512), determines the final pulse

length in the range of 256 to 511 (or 767) PCK cycles.

7-0

Vertical sync HIGH length. This 8-bit register holds a value extending from 0 to

255 PCK cycles.

7-0

CBL

Color bar length. This 8-bit register holds a value which is the length of each

color bar displayed extending from 0 to 255 PCK cycles.

FIELD

Field identification (read only). These three bits are updated 12 PXCK periods

after each VHSYNC. They allow the user to determine field type on a

continuous basis.

4-0

LTYPE

Line type identification (read only). These five bits are updates 5 PXCK periods

after each VHSYNC. They allow the user to determine line type on a continuous

basis.
