done by setting HLD HIGH on the
clock cycle after the clock cycle which
latches the last data value. It is
important that the LF Interface
remain disabled when not loading
data into it.
The horizontal coefficient banks may
only be loaded with the Horizontal
LF Interface
cient banks may only be loaded with
the Vertical LF Interface
Configuration and Control Registers

Since both LF Interfaces

LF Interfaces

the same time. Or, one LF Interface
can load the Configuration/Control
Registers while the other loads it’s
respective coefficient banks. If both
