starting with register B, sets ON
the bit position indicated by
lower n bits of A, and resets
OFF all other bits.

122 Bit count −
[ A BC B ]
− Counts the number of ON bits
of A and stores it in B.

147 Flip-flop S F/F Q
R A Sets ON device A when set
input (S) is ON, and resets OFF
device A when reset input (R) is
ON.
(Reset takes priority)

U U/D Q
C
E A While enable input (E) is ON,
counts up or down the number
of cycles the count input (C)
comes ON, depending on the
up/down select input (U).
Up when U is ON, down when U
is OFF.
