Operands
| Operand | Description |
|---|---|
| S | The first operand. Entries are WORD data registers. This is the starting data register to fetch data to transfer. The signed value range is -32,768 ~ 32,767 (216). The unsigned value range is 0 ~ 65,535 (216-1). The Hexadecimal value range is H0000 ~ HFFFF. |
| D | The second operand. Entries are only WORD data registers. This is where the bit value of S is moved to. |
| fm | The third operand. Entries are Hexadecimal constants. This is the format for transferring S data to the data register, D. Please refer to the table below for Hexadecimal formatting. |
Assign fm
| Hexadecimal Value | Description |
|---|---|
| H | Must be used for Hexadecimal notation. |
| 0 ~ F | Bit address of S to be transferred. |
| 0 ~ F | Bit address of D to save S to. |
| 0 | This slot is NOT used. Leave as 0. |
| 1 ~ F | The number of bits to be transferred (1 ~ 15). |
| Example | H120B |
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.
F11.0 turns ON when the value of the data for transferring S exceeds the value range of the data register D.
Instruction Behavior
The WBMOV and WBMOVP instructions behave as follows:
- The instructions will not execute if the least significant bit (last digit) of FM is 0.
- Transferring data registers is possible even in the case of overlap between the data registers S and D.
- Overlap can happen when the number of transferred data registers is larger than the distance between the data registers S and D.
