- | The divh instructions of the device should be specified in the following formats. |
- | In asrh, the following formats can also be used in addition to the above. |
- | If the instruction is executed in syntax "divh imm, reg2", and the following expression is specified for imm, the assembler executes instruction expansion to generate multiple machine instructions. |
(a) | Absolute expression having a value of other than 0 within the range of -16 to +15 |
|
|
|
divh imm5, reg
|
mov imm5, r1
divh r1, reg
|
(b) | Absolute expression exceeding the range of -16 to +15, but within the range of -32,768 to +32,767 |
|
|
|
divh imm16, reg
|
movea imm16, r0, r1
divh r1, reg
|
(c) | Absolute expression having a value exceeding the range of -32,768 to +32,767 |
If all the lower 16 bits of the value of imm are 0
