Description: Arithmetically shifts the contents of general register Rn to the right by one bit, and
stores the result in Rn. The bit that is shifted out of the operand is transferred to the T bit (figure
6.9).
Operation:
Example:
Format
SHAR Rn
SHAR(long n) /* SHAR Rn */
{
}
SHAR
long temp;
if ((R[n]&0x00000001)==0) T=0;
else T=1;
if ((R[n]&0x80000000)==0) temp=0;
else temp=1;
R[n]>>=1;
if (temp==1) R[n]|=0x80000000;
else R[n]&=0x7FFFFFFF;
PC+=2;
