The condition register (CR) is a 32-bit register that reflects the result of certain operations and provides a
mechanism for testing and branching. The bits in the CR are grouped into eight 4-bit fields: CR0 to CR7.
The CR fields can be set in the following ways:

Field
Specified fields of the CR can be set by an instruction (mtcrf) to move to the CR from a GPR.
Specified fields of the CR can be moved from one CRx field to another with the mcrf instruction.
A specified field of the CR can be set by an instruction (mcrxr) to move to the CR from the XER.
Condition register logical instructions can be used to perform logical operations on specified bits
in the condition register.
CR0 can be the implicit result of an integer operation.
