GDB — Gate or Drain/Source Select Bit
The read-always GDB bit selects gate, source, or drain for voltage
modulation. GDB is writable when the SES bit is clear.
GDB selects the gate, source, or drain. In programming, GDB selects
gate (GDB = 1) or drain (GDB = 0) voltage for amplitude modulation.
When PAWS[2] = 0, mask plugs control amplitude modulation. When
PAWS[2] = 1, the PAWS[1:0] bits control amplitude modulation.
1 = Gate selected
0 = Drain/source selected
