Signal Definitions
HRSL3-0 — Horizontal Round/Select/Limit Control
HRSL3-0 determines which of the sixteen user-programmable Round/Select/Limit registers (RSL registers)
are used in the horizontal Round/Select/Limit circuitry (RSL circuitry). A value of 0 on HRSL3-0 selects RSL
register 0. A value of 1 selects round/select/limit register 1 and so on. HRSL3-0 is latched on the rising
edge of CLK (see the horizontal round, select, andv limit sections for a complete discussion).
VRSL3-0 — Vertical Round/Select/Limit Control
VRSL3-0 determines which of the sixteen user-programmable RSL registers are used in the vertical RSL
circuitry. A value of 0 on VRSL3-0 selects RSL register 0. A value of 1 selects RSL register 1 and so
on. VRSL3-0 is latched on the rising edge of CLK (see the vertical round, select, and limit sections for
a complete discussion).
OE — Output Enable
When OE is LOW, DOUT11-0 is enabled for output. When OE is HIGH, DOUT11-0 is placed in a
high-impedance state.
HPAUSE — LF InterfaceTM Pause
When HPAUSE is HIGH, the Horizontal LF Interface
to a LOW state. This effectively allows the user to load coefficients and Control Registers at a slower rate
than the master clock (see the LF Interface
VPAUSE — LF InterfaceTM Pause
When VPAUSE is HIGH, the Vertical LF Interface
a LOW state. This effectively allows the user to load coefficients and Control Registers at a slower rate than
the master clock (see the LF Interface
