Product data sheet
separate bytes (where the hardware sets the upper bits to 00b). For transfer over I-port
the result is buffered into a dedicated VBI data FIFO with a capacity of 2
(2
The programming registers 40h to 5Fh control the VBI data slicing and data transfer.
Registers 40h and 58h control the slicing process itself. The Line Control Registers (LCR)
define the data type (VBI data standard) to be decoded. The assignment of the LCR
registers to the CVBS input lines depends on the parameter VOFF.
