31 24 23 16 15 8 7 EAX Parts of the EAX register can be addressed separately from the whole. The low-order word, bits 0-15, is known as AX. 31 24 23 16 15 EAX AX The instruction sub ax, 10 subtracts 10 from the word stored in AX, without changing any of the high-order bits (16-31) of EAX. Similarly, the low-order byte (bits 0–7) and the high-order byte (bits 8–15) of AX are known as AL and AH, respectively. 31 24 23 16 15 87 EAX AH AL
