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

Operation:
Description: Jump to the subroutine at the 16-bit absolute address in program memory
specified in the instruction’s 24-bit extension word if the n
clear. The bit to be tested is selected by an immediate bit number from 0–23. If the n
of the source operand S is clear, the address of the instruction immediately following the
JSCLR instruction (PC) and the system status register (SR) are pushed onto the system
stack. Program execution then continues at the specified absolute address in the instruc-
tion’s 24-bit extension word. If the specified memory bit is not clear, the program counter
(PC) is incremented and the extension word is ignored. However, the address register
