RE: [AVR-Chat] Why does "ldi r24, 0x74;" become "84 e7" (and "ldi r24, 0x70; " become "80 e7") Got it, sorry. 2011-12-27 by Tim Mitchell The AVR opcodes are 16-bit, so the 0x70 does indeed get spread across 2 bytes. The Atmel "AVR Instruction Set" pdf tells you how each opcode is encoded. -- Tim Mitchell [Non-text portions of this message have been removed]
