((SP)) ← (IP)
(IP) ← op2
Description
Pushes the word specified by operand op1 and the value of the instruction pointer, IP,
onto the system stack, and branches to the absolute memory location specified by the
second operand op2. Because IP always points to the instruction following the branch
instruction, the value stored on the system stack represents the return address of the
calling routine.
CPU Flags
E Set if the value of the pushed operand op1 represents the lowest
possible negative number. Cleared otherwise. Used to signal the end of a
table.
Z Set if the value of the pushed operand op1 equals zero. Cleared
otherwise.
V Not affected.
C Not affected.
N Set if the most significant bit of the pushed operand op1 is set. Cleared
otherwise.
