AH500 Programming Manual API 0219 Symbol: S ： Data source Word/Double word n ： Number of bits Word/Double word D ： Data destination Word/Double word Explanation: 1. The operand D used in the 16-bit instruction occupies sixteen 16-bit registers, i.e. D ~ D +15. 2. The operand D used in the 32-bit instruction occupies thirty-two 32-bit registers, i.e. D ~ D +31. 3. The operand n indicates that the values of the bits in the operand S are stored in the n th bits in the operand D . Besides, the operand n used in the 16-bit instruction should be within the range between 0 and 15, and the operand n used in the 32-bit instruction should be within the range between 0 and 31. 4.
The operand n used in the 16-bit instruction indicates that the values of the bits in S are stored in the n th bits in D ~ D +15 in order. 5. The operand n used in the 32-bit instruction indicates that the values of the bits in S are stored in the n th bits in D ~ D +31 in order. 6. Only the 32-bit instructions can use the 32-bit counter. 7. Take the 16-bit instruction for example. b15 b0 S . .. . . . . . 0 D D+1 D+2 . . . . . . . . . . . .
