Description: Jump to the 16-bit absolute address in program memory specified in the
instruction's 24-bit extension word if the n
be tested is selected by an immediate bit number from 0–23. If the specified memory bit
is not set, the program counter (PC) is incremented, and the absolute address in the
extension word is ignored. However, the address register specified in the effective
address field is always updated independently of the state of the n
ister indirect addressing modes may be used to reference the source operand S. Abso-
lute short and I/O short addressing modes may also be used.
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.
