Shift register
D SR Q
S (n)
E A
When shift input (S) comes ON,
shifts the data of specified shift
register 1 bit to the left, and
stores data input (D) state into
A. This operation is enabled
while enable input (E) is ON.
The carry flag changes
according to the result.
Shift register: n devices starting
with device A.

L A
When shift input (S) comes ON,
shifts the data of specified shift
register 1 bit to the left or to the
right depending on direction
input (L). This operation is
enabled while enable input (E) is
ON. The carry flag changes
according to the result.
