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. It takes about 5 ms before the
XO_ENA is set to 1 and the XO output becomes stable. When this
signal becomes 1, software must wait additional 3 ms before it can
use the XO output for frequency counting. See the XO_CTRL test
register.
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.
Thermal Random Number Generator (Rng) Output Bit.
Note that the temperature sensor must be enabled in order to get an inter-
esting result here.
Output of the Phase Detection Comparator at the PA Output.
Output of phase detection PA comparator. When PA is enabled, runs at full
clock rate, and is asynchronous to clk_sys. Should be demetastabilized suf-
ficiently by transferring to another register for purposes of getting to CPU.
