3.2.8 P r o g r a m Control Instructions
M O T O R O L A
" Letters
A set of subroutine call and return instructions and conditiona and uncon-
ditional branch instructions perform program control operations. The no
operation instruction (NOP) may be used to force synchronization of the
internal pipelines. Table 3-8 summarizes these instructions.
