This instruction executes a software trap. The Program Counter and Flags are pushed onto
the stack. The eZ8 CPU loads the 16-bit Program Counter with the value stored in the Trap
Vector Pair. Execution begins from the new value in the Program counter. Execute an
IRET instruction to return from a trap.
There are 256 possible Trap Vector Pairs in Program Memory. The Trap Vector Pairs are
numbered from 0 to 255. The base addresses of the Trap Vector Pairs begin at
end at
tiplying the vector by 2.
