When both process B and process D have finished (i.e., when SW5 and SW6
turn ON), processes B and D are reset together by the SNXT(009) at the end of
the programming for process B. Although there is no SNXT(009) at the end of
process D, the control bit for it is turned OFF by executing SNXT(009) 050004.
This is because the OUT for bit 050003 is in the step reset by SNXT(009)
050004, i.e., bit 050003 is turned OFF when SNXT(009) 050004 is executed.
Process B is thus reset directly and process D is reset indirectly before executing
the step for process E.
