that latches the HIGH to LOW transition
of LD. The next value(s) loaded into the
interface are the data value(s) which will
be stored in the bank or register defined
by the address value. When loading
coefficient banks, the interface will expect
ten values to be loaded into the device
after the address value. The ten values are
coefficients 0 through 8 and the Keyscale
coefficient. When loading Configuration
or Bias Registers, the interface will expect
one value after the address value. When
loading RSL registers, the interface will
expect four values after the address value.
When loading gamma look-up tables, the
interface will expect 1024 values after the
address value. When loading HBLANK
flag counts, the interface will expect 2
values after the address value.
The coefficient banks, configuration
registers, RSL registers, etc., are not
loaded with data until all data values for
the specified address are loaded into the
LF Interface. In other words, the coeffi-
cient banks are not written until all ten
coefficients have been loaded into the LF

CLK
In this example, the Output Multiplexer is in a mode where the delay through the section is 2 CLK cycles. Only one channel is shown in this example,
however, the other three channels behave in the same manner. The example assumes that the bypass RAM length is set to the length of the core data path.
W1: Bypass data is output to the output port and replaces core data.
W2: Core data is output to the output port and replaces bypass data.
