The Move Register (MOVR) instruction copies the specified source register to the specified destination register and sets or clears the [[Sign Flag]] and [[Zero Flag]] according to the value that was copied. This instruction uses 6 [[CP1610]] clock cycles in all cases except where the destination register is either R6 or R7, in which case it will use 7 clock cycles.<br/>
