Description: Jump to the location in program memory given by the instruction’s effective
address if the specified condition is true. If the specified condition is false, the program
counter (PC) is incremented and the effective address is ignored. However, the address
register specified in the effective address field is always updated independently of the
specified condition. All memory alterable addressing modes may be used for the effec-
tive address. A Fast Short Jump addressing mode may also be used. The 12-bit data is
zero extended to form the effective address. See Section A.9 for restrictions. The term
“cc” may specify the following conditions:
