• Manufacturer Part Number: dsp56000
• Description: 24-bit Digital Signal Processor Family Manual
• Manufacturer: Freescale Semiconductor, Inc

Operation:
Description: Transfer data from the specified source register S1 to the specified desti-
nation accumulator D1 if the specified condition is true. If a second source register S2
and a second destination register D2 are also specified, transfer data from address reg-
ister S2 to address register D2 if the specified condition is true. If the specified condition
is false, a NOP is executed. The term “cc’’ may specify the following conditions:
where
U denotes the logical complement of U,
When used after the CMP or CMPM instructions, the Tcc instruction can perform many
useful functions such as a “maximum value,” “minimum value,” “maximum absolute
value,” or “minimum absolute value” function. The desired value is stored in the destina-
