6.1.47
Description: Rotates the contents of general register Rn and the T bit to the left 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
6.3).
Operation:
Example:
Format
ROTCL Rn
ROTCL(long n) /* ROTCL Rn */
{
}
ROTCL
long temp;
if ((R[n]&0x80000000)==0) temp=0;
else temp=1;
R[n]<<=1;
if (T==1) R[n]|=0x00000001;
else R[n]&=0xFFFFFFFE;
if (temp==1) T=1;
else T=0;
PC+=2;
