3.3  Input STOP

When a STOP signal is input to the R/W Module, receiving and processing of
commands and command processing will stop and then, after the STOP signal is
deactivated, the Module will be on stand by for new commands. When the STOP
signal is input, oscillation will stop regardless of the setting of the oscillation control
mode.
If a STOP signal is input more than 50 msec prior to shut down, writing of unstable
data to the Tag may be prevented. However, if writing of the command in process
requires more than one page, not all pages may be completely rewritten.

3.4  Memory Management on Tag

The Tags used to conduct communication with the R/W Module may be one of the
following two types depending on memory capacity: 128 bytes (user area 112 bytes)
or 256 bytes (user area 240 bytes). The memory area recognizes every 8 bytes as
one page, distinguished by such addresses as 00h ~ 07h, 08h ~ 0Fh, and so on.
