Operation Flow

By repeating "stand-by mode" and "sleep mode", the power consumption at the RF circuit is reduced. Duration
of the "stand-by mode" and "sleep mode" can be set by REG22, bit 1 of REG24 and REG25.
Current Consumption
If the FDP03 receives data that destination address is matched and REG18 (address check) is set to "
destination address check at reception"
duration is set by REG21 or command setting. When the FDP03 cannot receive next data packet during the
extended stand-by time, it becomes "sleep mode".
