Description
this value must not be changed
selects the source for the modulator input:
modulator input is LOW
modulator input is HIGH
modulator input is the internal encoder
modulator input is pin MFIN
this value must not be changed
delivers an inverted 13.56 MHz energy carrier output
signal on pin TX2
delivers a continuously unmodulated 13.56 MHz
energy carrier output signal on pin TX2
enables modulation of the 13.56 MHz energy carrier
the output signal on pin TX2 is the 13.56 MHz energy
carrier modulated by the transmission data
TX2 is driven at a constant output level
the output signal on pin TX1 is the 13.56 MHz energy
carrier modulated by the transmission data
TX1 is driven at a constant output level
