Note: For JMPA instruction, a pre-fetch hint bit is used (the instruction bit 9 = l). This bit
is required by the fetch unit to deal efficiently with short backward loops. It must
be set if 0 < IP_jmpa - IP_target <= 32, where IP_jmpa is the address of the JMPA
instruction and IP_target is the target address of the JMPA. Otherwise, bit 9 must
be cleared.
