Description
The value of this register defines the conductance of the output
N-driver during times of no modulation. This may be used to regulate
the output power and subsequently current consumption and
operating distance.
Note: The conductance value is binary weighted.
Note: During soft Power-down mode the highest bit is forced to 1.
Note: This value is only used if the driver TX1 or TX2 are switched on.
Otherwise the value of the bits CWGsNOff of register GsNOffReg is
used.
The value of this register defines the conductance of the output
N-driver for the time of modulation. This may be used to regulate the
modulation index.
Note: The conductance value is binary weighted.
Note: During soft Power-down mode the highest bit is forced to 1.
Note: This value is only used if the driver TX1 or Tx2 are switched on.
Otherwise the value of the bits ModsNOff of register GsNOffReg is
used.
