|---|---|
| S | The first operand. Entries are DWORD data registers or constants. This is the data register to count set bits. The signed value range is -2,147,483,648 ~ 2,147,483,647 (232). The unsigned value range is 0 ~ 4,294,967,295 (232-1). The Hexadecimal value range is H00000000 ~ HFFFFFFFF. |
| D | The second operand. Entries are only WORD data registers. This represents the number of set bits found. The value will range from 0 ~ 32. |
Notice
Error Flag (F11.0) Notice
The error flag, F11.0, will be ON for one scan when the address of the data register assigned by @D exceeds the range of the data register, D. The range of the data register, D, is dependent on the CPU type.
