Read as 0x0. Write has no effect.
GPIO LED Drive.
Actual status of the LED drive. If this bit is at 1, then the LED driver is
actually on. The LED driver is controlled by P0.5 bit and the intensity value in
PORT_CTRL register. If the P0.5 bit is read, then it returns user LED
drive request, which does not reflect the actual LED driver status.
Crystal Oscillator Clock Good.
Crystal oscillator XO output is stable.
ODS Empty.
Supplementary flag indicating that the ODS Tx holding register is
empty. It can be used as an indication for software to write a new
data byte to ODS_DATA register to transmit. This applies to the Tx
holding register only. See ODS_NODATA for the flag related to the
actual Tx shift register.
ODS No Data.
Supplementary flag that the output digital serializer (ODS) Tx shift
register ran out of data and there is nothing else to transmit.
Reserved. Can read either 0 or 1.
