Dual RF LDMOS Bias Controller with
Nonvolatile Memory
FIFOEMP is set to 1 when the FIFO is empty. Once data
is placed into the FIFO, FIFOEMP is set to 0.
When in ADC monitoring mode, FIFOOVER is set to 1
when a FIFO overflow occurs. FIFOOVER remains at 1,
even if the FIFO is subsequently read and no longer
full. FIFOOVER is reset by reading the Flag register.
When in LUT streaming mode or message mode, the
FIFO is not permitted to overflow and FIFOOVER then
denotes when the FIFO is full. FIFOOVER is set to 1
when the FIFO is full and immediately returns to 0 once
a data word is moved out of the FIFO.
HIGHI_ is set to 1 when the individual channel 1 and
channel 2 current-sense measurements exceed the
individual channel 1 and channel 2 high current thresh-
old and returns to 0 after the Flag register is read.
HIGHI2 is replaced by HIGHT2 when the INTEMP2 bit
is set in the Alarm Hardware Configuration register.

FUNCTION
Acquisition/tracking bit. Set to 0 to force the next current-sense calibration
0
to run in acquisition mode. Set to 1 to force the next calibration to run in
tracking mode. Set TRACK to 0 the first time through a calibration.
0
Single calibration select bit. Set to 1 perform single or self-timed
calibrations of PGA1 and PGA2. DOCAL resets to 0 after calibration.
Self-timed calibration select bit. Set to 1 to perform calibrations of PGA1
0
and PGA2 on a self-timed periodic basis (approximately every 13ms).
When set to 0, calibrations only occur when DOCAL is set to 1.
