3.1. Data Transfer Mode.................................................................................................................................. 7
FDP03 has 2 kinds of data transfer mode. One is "Interchange" mode that is possible to exchange data
between other FDP series. Another is "Communication Distance Extend" mode. The initial setting is
"Interchange" mode......................................................................................................................................... 7

Setting by the memory register ....................................................................................................... 7
The data transfer mode can be changed by the bit 5 of the REG10. The initial setting of the bit 5 is "0".
It means that "Interchange" mode. For more detail, please check Section 8. .............................................. 7

5. Low Power Stand-by Mode.................................................................................................................... 13
This mode realizes low power consumption drive by switching ON and Off of RF circuit. It is possible to
set this low power stand-by mode by the memory register (REG21: bit 2) or the command. If this mode is
set by the command, this mode is released by the main power OFF or by set to power down mode. .......... 13
