Instruction Set (continued)
5.1.3 Control Instructions
Table 26 shows control instructions and their required numbers of instruction cycles and program-memory words.
Required instruction cycles and program-memory words vary according to whether each instruction is executed
unconditionally or conditionally. Control instructions cannot be executed from the cache.
With the exception of ireturn, the control instructions in Table 26 can be executed conditionally. For example:
if le goto 0x0345

goto JA*
goto pt
call JA*
call pt
return (goto pr)
* The goto JA and call JA instructions should not be placed in the last or next-to-last instruction before the
boundary of a 4 Kword page. If the goto or call is placed there, the program counter increments to the next page
and the jump is to the next page rather than the desired current page.

ireturn (goto pi)
The ireturn instruction can only be executed unconditionally.
