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

Explanation of Example: Prior to execution, the 24-bit X location X:$FFE4 (I/O port B
data register) contains the value $FFFFFF. The execution of the BCLR #$E,X:<<$FFE4
instruction tests the state of the 14th bit in X:$FFE4, sets the carry bit C accordingly, and
then clears the 14th bit in X:$FFE4.
