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
5 GPIO_LED_DRIVE 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.

XO_CKGOOD
Crystal Oscillator Clock Good.
Crystal oscillator XO output is stable.
ODS Empty.
Supplementary flag indicating that the ODS Tx holding register is

ODS_EMPTY
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.
2
ODS_NODATA Supplementary flag that the output digital serializer (ODS) Tx shift
register ran out of data and there is nothing else to transmit.
