BYTEx operand
| | Description | Keil, Inc. The BYTEx operators return the byte of operand corresponding to the position specified by x. For example, BYTE0 returns the least-significant byte, BYTE1 returns the next byte, and so on. The following table shows how the BYTEx, WORDx, HIGH, and LOW controls work on a 32-bit value. | MSB | 32-bit operand | LSB |
|---|
| BYTE3 | BYTE2 | BYTE1 | BYTE0 | | WORD2 | WORD0 | | | HIGH | LOW |
The operand must either be absolute or a constant defined as extern :DATAn. Other types of relocatable operands are not allowed. Note - The BYTE0, BYTE1, BYTE2, BYTE3, BYTE4, BYTE5, BYTE6, and BYTE7 operators are available with the A166 Assembler.
Note - This directive is available in the AX51 Assembler only.
