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

Restrictions: A JSET instruction used within a DO loop cannot specify the loop
address (LA) as its target.
A JSET located at LA, LA–1, or LA–2 of a DO loop cannot specify the program controller
registers SR, SP, SSH, SSL, LA, or LC as its target.
JSET SSH or JSET SSL cannot follow an instruction that changes the SP.
A JSET instruction cannot be repeated using the REP instruction.
Example:
Explanation of Example: In this example, program execution is transferred to the
address P:$4321 if bit 12 (SCI COD) of the 16-bit read/write I/O register X:$FFF2 is a
one. If the specified bit is not set, no jump is taken and the program counter (PC) is incre-
mented by 1.
Condition Codes:
For destination operand A or B:
For other source operands:
The condition codes are not affected.
