5.2.4.3.2 Branch Instructions
Table 5-12 lists the branch instructions. To simplify assembly language programming, a set of simplified
mnemonics and symbols is provided for the most frequently used forms of branch conditional, compare,
trap, rotate and shift, and certain other instructions. See Appendix F, "Simplified Mnemonics," in the
Programming Environments Manual for a list of simplified mnemonics.

5.2.4.3.3 Condition Register Logical Instructions
Condition register logical instructions, shown in
(mcrf) instruction are also defined as flow control instructions.
Name
Condition Register AND
Condition Register OR
Condition Register XOR
Condition Register NAND
Condition Register NOR
Condition Register Equivalent
Condition Register AND with Complement
Condition Register OR with Complement
Move Condition Register Field
Note that if the LR update option is enabled for any of these instructions, these forms of the instructions
are invalid in the MPC885.
5.2.4.4 Trap Instructions
The trap instructions shown in
the conditions tested by a trap instruction are met, the system trap handler is invoked. If the tested
conditions are not met, instruction execution continues normally.
