Rabbit 3000A InstructionInstruction Reference Manual 137DescriptionThe System/User Mode Register, SU, is an 8 bit register that forms a stack of the current processor mode andthe previous 3 modes. SETUSR shifts the contents of SU 2 bits to the left, then sets bit 1 to 0 and bit 0 to 1,signifying user mode.This instruction is privileged and only implemented for the Rabbit 3000A.SETUSROpcode Instruction Clocks OperationED 6F SETUSR 4 (2,2) SU={SU[5:0],0x01}Flags ALTD I/OS Z L/V C F R SP S D- - - -
