Format
ROTCR
Description
Rotates the contents of general register Rn and the T bit 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 6.4).
Operation
Examples:
ROTCR(long n) /* ROTCR Rn */
{
}
ROTCR R0
long temp;
if ((R[n]&0x00000001)==0) temp=0;
else temp=1;
R[n]>>=1;
if (T==1) R[n]|=0x80000000;
else R[n]&=0x7FFFFFFF;
if (temp==1) T=1;
else T=0;
PC+=2;
