AH500 Programming Manual API 0218 Symbol: S ： Data source Word/Double word n ： Number of bits Word/Double word D ： Data destination Word/Double word Explanation: 1. The operand S used in the 16-bit instruction occupies sixteen 16-bit registers, i.e. S ~ S +15. 2. The operand S used in the 32-bit instruction occupies thirty-two 32-bit registers, i.e. S ~ S +31. 3. The operand n indicates that the value of the n th bit in every piece of data in the operand S is retrieved. 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 n th bits in S ~ S +15 are retrieved, and the values of the n th bits are stored in the operand D in order. 5. The operand n used in the 32-bit instruction indicates that the values of the n th bits in S ~ S +31 are retrieved, and the values of the n th bits are stored in the operand D in order. 6. Only the 32-bit instructions can use the 32-bit counter. 7. Take the 16-bit instruction for example. 0 S S+1 S+2 . . . S+13 S+14 S+15 b15 b0 D ...... . .
