• When the status of a touch switch changes because it has been touched or
released, notifies the change of status to the host.
• Normally, one command notifies the change in status of one allocated bit only,
but when multiple bits in the same word change simultaneously, those
changes are all notified together with one command.

Changed word number : 0102CH
Contents of the word after the change (hexadecimal):
3013H (binary notation: 0011 0000 0001 0011)
Changed bit information (hexadecimal):
0001H(binary notation: 0000 0000 0000 0001)
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.)
