- | The cmpf.d and cmpf.s instructions of the device should be specified in the format of "cmpf.* fcond, reg2, reg1, fcbit". |
In asrh, they can also be specified in the format of "cmpffcond.* reg2, reg1, fcbit". Code that can be specified in cmpffcond and the result of assembly are shown in Table 5.29.
