Instruction Set Architecture—IP2022 User’s Manual 204 www.ubicom.com RR fr Rotate fr Right through Carry into fr Operation: C || fr = fr || C Bits affected: C Opcode: 0011 001f ffff ffff Description: This  instruction  rotates  the  bits  of  the  specified
data memory location right through the C bit and
moves  the  8-bit  result  into  the  data  memory
location. The  bits  obtained  from  the  register  are  shifted
right by one bit position. C is shifted into the most
significant bit position and the least significant bit
is  shifted  out  into  C,  as  shown  in  the  diagram
below. Cycles: 1 515-045.eps Data Memory Location
