As a Reduced Instruction Set Computer (RISC) the PowerPC does not implement bit set and clear instructions. A bit set/clear instruction requires that the memory location be read, modified and then written back in a single operation. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Khairul Nizam How can i do a bit control with mpc555 since there is no specific instruction set to do it like the 68hc11.I really need it for switching purpose,to avoid other bit to be affected.
