Operating instructions for those missing the AVR is easy to prove that the code efficiency should be the
realization that we have to find a command instructions and omitted a good way to compromise between
Q: Why did not EORI instruction?
All AVR instructions A few exceptions are two-byte length which means that only 65,536 (64K) possible
combinations to arrange the AVR instruction set, instruction set, when we take the specified number of
compromises to the fullest possible Unlike the use of these combinations 64K CISC instruction can be a
microcontroller, two, three or more bytes of the structure of the AVR instructions we can not achieve all of
examples like this as an immediate address register and contains all 32 address 8-bit instructions and registers
a constant need to address the need for other five all this instruction will occupy space in the 8K instruction
mix in other words we can only be eight such instructions are no more instructions can be achieved while be a
length of 17 instructions is not economical and convenient scheme will not be considered in the design process
AVR instruction set we listened to a lot of set building meaning we turned to experts in their C compiler,
instruction set on how to adjust to fit C compiler, a number of suggestions put forward as an example the
compiler experts suggest that we brought into place for the immediate SBCI sacrifice ADDI instruction
subtraction
Operating instructions for those missing the AVR is easy to prove that the code efficiency should be the

Q: I use "sbr r30, 3" instruction set in the register 30, bit D3 of the D3 bit does not work but if bit D0 and
D1, the practice can be set where I have wrong?
A "SBR" can be used both in a register set number (like "CBR" can be used to clear the register at the same time
a number of) command of the second parameter is not specified in the item number but the number of registers
used and for logic or operations in this case, the contents of $ 03 and R30 resulting in a minimum-phase or
arm board
two-bit bit to just set the D3 one should try the following methods
