Description
defines the conductance of the output n-driver during periods without
modulation which can be used to regulate the output power and
subsequently current consumption and operating distance
Remark: the conductance value is binary-weighted
during soft Power-down mode the highest bit is forced to logic 1
value is only used if driver TX1 or TX2 is switched on
