Individual Instruction Descriptions
4-88
Description If cc condition in Table 4–48 is true, PC + 2 is pushed onto the stack and the
second word operand is loaded into the PC. If the condition is false, execution
defaults to a NOP. A C
cc instruction cannot be followed by a return (RET)
instruction. No restriction applies if IRET is used instead of RET.
