I, Q, M, SM, T, C, V, S, L
Boolean
N

Boolean
SHRB instruction moves the DATA value to the shift
register. S_BIT specifies the lowest bit of the shift
register.N specifies the length of the shift register and the
shift direction (shift plus = N, shift minus = - N).The moved
out bit is placed in the overflow memory bit (SM1.1).The
instruction is defined by S_BIT and N.
error conditions:
0006
Indirect address
0091
Operating number is out of range
0092
Count field error
Special memory bit:
SM1.1
Overflow bit
Example:
When the value of M0.0 is 1 ， the value of M10.0 is moved to V0.0 ， the value of V0.0 is moved to V0.1 ， the value of V0.1 is moved to V0.2 ， the value of V0.2 is moved to V0.3 ， the value of V0.3 is moved to SM1.1.
If N is negative, the shift direction is opposite.
