Description
The value of this register defines the conductance of the output
N-driver during times of no modulation.
Note: The conductance value is binary weighted.
Note: During soft Power-down mode the highest bit is forced to 1.
Note: The value of the register is only used if the driver is switched
off. Otherwise the bit value CWGsNOn of register GsNOnReg is
used.
Note: This value is used for LoadModulation.
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: The value of the register is only used if the driver is switched
off. Otherwise the bit value ModGsNOn of register GsNOnReg is
used
Note: This value is used for LoadModulation.
