Description
Set to logic 1, the output signal at pin TX2 will be inverted, if driver TX2
is enabled.
Set to logic 1, the output signal at pin TX1 will be inverted, if driver TX1
is enabled.
Set to logic 1, the output signal at pin TX2 will be inverted, if driver TX2
is disabled.
Set to logic 1, the output signal at pin TX1 will be inverted, if driver TX1
is disabled.
Set to logic 1, the output signal on pin TX2 will deliver continuously the
un-modulated 13.56 MHz energy carrier.
Set to logic 0, Tx2CW is enabled to modulate the 13.56 MHz energy
carrier.
Set to logic 1, Tx2RFEn and Tx1RFEn can not be set if an external RF
field is detected. Only valid when using in combination with bit
Tx2RFEn or Tx1RFEn
Set to logic 1, the output signal on pin TX2 will deliver the 13.56 MHz
energy carrier modulated by the transmission data.
Set to logic 1, the output signal on pin TX1 will deliver the 13.56 MHz
energy carrier modulated by the transmission data.
