ACC — Accumulator Control
When ACC is HIGH, the accumulator
is enabled for accumulation and the
accumulator output register is
disabled for loading. When ACC is
LOW, no accumulation is performed
and the accumulator output register
is enabled for loading. ACC is
latched on the rising edge of CLK.
SHEN — Shift Enable
SHEN enables or disables the
loading of data into the input/
cascade registers and the line
buffers. When SHEN is LOW, data
is loaded into the input/ cascade
registers and shifted through the
line buffers on the rising edge of
CLK. When SHEN is HIGH, data
can not be loaded into the input/
cascade registers or shifted through
the line buffers and their contents
will not be changed.
RSL
3-0
— Round/Select/Limit Control
RSL
3-0
determines which of the
sixteen user-programmable round/
select/ limit registers are used in the
round/ select/ limit circuitry. A
value of 0 on RSL
3-0
selects round/
select/ limit register 0. A value of 1
selects round/ select/ limit register 1
and so on. RSL
3-0
is latched on the
rising edge of CLK (see the round,
select, and limit sections for a
complete discussion).
OED — DOUT Output Enable
When OED is LOW, DOUT
15-0
is
enabled for output. When OED is
HIGH, DOUT
15-0
is placed in a
high-impedance state.
OEC — COUT Output Enable
When OEC is LOW, COUT
15-0
is
enabled for output. When OEC is
HIGH, COUT
15-0
is placed in a high-
impedance state.
