DEVICES INCORPORATED
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

the line buffers and their contents
will not be changed.
