Note: IRQ pin may also be configured as open collector. In that case the values for VOH do not apply.

22.4.3 ANTENNA DRIVER OUTPUT PIN CHARACTERISTICS

The source conductance of the antenna driver pins TX1 and TX2 for driving the HIGH level can be

configured via GsCfgCW in the CwConductance Register, while their source conductance for driving the

LOW level is constant.

For the default configuration, the output characteristic is specified below:
