The overwrite control area consists of 3 bytes from the start address. The decre-
ment value from the overwrite count is written in this area, and if this value is 0 an
end code 76 will be given as a warning. The remaining overwrite count will be
written into the control area in hexadecimal. This can be read with the READ
command.
If the control area data is already 0, the control area value will not be refreshed,
and only a warning will be given in response. When the decrement count is set
as "00 ," the count will not be updated, and only a overwrite count check will be

performed.
