CSR
Operation
n = RS or IMM4
Shifts the bits in register RD n positions to the right. The higher n bits of the register RD become filled
with the carry flag. The carry flag will be updated to the bit contained in RD[n-1] before the shift for n > 0.
n can range from 0 to 16.
In immediate address mode, n is determined by the operand IMM4. n is considered to be 16 if IMM4 is
equal to 0.
In dyadic address mode, n is determined by the content of RS. n is considered to be 16 if the content of RS
is greater than 15.

Set if bit 15 of the result is set; cleared otherwise.
Set if the result is $0000; cleared otherwise.
Set if a two´s complement overflow resulted from the operation; cleared otherwise.
RD[15]
Set if n > 0 and RD[n-1] = 1; if n = 0 unaffected.
