Changed word number
Contents of the word after the change (hexadecimal):
Changed bit information (hexadecimal):
Check sum (hexadecimal)
From the "changed word number" and "changed bit information", it is ascertained
that the change relates to the touch switch allocated to bit 00 of word 0102CH, and
because "1" is set at the relevant position in the "contents of the word after the
change", it is ascertained that the touch switch has been pressed (if the change is
to "OFF", since the operation differs according to the type of touch switch, it cannot
be determined from a change in the bit status alone whether the touch switch has
been touched or released.)
