Places the complemented result of ORing two Condition Register bits in a Condition Register bit.
| crnor | BT,BA,BB |
See "Extended Mnemonics of Condition Register Logical Instructions" for more information.
The crnor instruction logically ORs the Condition Register bit specified in BA and the Condition Register bit specified by BB and places the complemented result in the target Condition Register bit specified by BT.
The crnor instruction has one syntax form and does not affect the Fixed Point Exception Register.
| BT | Specifies target Condition Register bit where result of operation is stored. |
| BA | Specifies source Condition Register bit for operation. |
| BB | Specifies source Condition Register bit for operation. |
The following code logically ORs Condition Register bits 8 and 4 and stores the complemented result into Condition Register bit 4:
# Assume Condition Register bit 8 is 1. # Assume Condition Register bit 4 is 0. crnor 4,8,4 # Condition Register bit 4 is now 0.
