Shift
72 m bit file n bits shift right
When (B) is a register:
Takes the m-word table headed by (B), and shifts it
to the right (low address direction) by the number of
words indicated by (A).
When (B) is a device:
Takes the m-bit file headed by (B), and shifts it to the
right (LSB direction) by the number of bits indicated
by (A). The carry flag changes according to the
result.
4~5 ∗
73 m bit file n bits shift left
When (B) is a register:
Takes the m-word table headed by (B), and shifts it
to the left (high address direction) by the number of
words indicated by (A).
When (B) is a device:
Takes the m-bit file headed by (B), and shifts it to the
left (MSB direction) by the number of bits indicated
by (A). The carry flag changes according to the
result.
4~5 ∗
74 Shift register
If the enable input (E) is ON, then when the shift
input (S) comes ON, the instruction takes the
contents of the n devices headed by the device (A)
and shifts them 1 bit to the left. The carry flag
changes according to the result.

75 Bidirectional shift register
If the enable input (E) is ON, then when the shift
input (S) comes ON, the instruction takes the
contents of the n devices headed by the device (A)
and shifts them 1 bit to the left or to the right (the
shift direction depends on the state of the direction
input (L)). The carry flag changes according to the
result.

76 Device shift
Takes the contents of the device ((A)-1) which
immediatety precedes the device (A), stores them in
(A), and sets (A)-1 to 0
