ROM table data read register. Data from the register at the address programmed into the
TFA[3:0] bits are written to this register for reading by the host processor.
Power-on-reset indicator:
1 = Power has been reset since last read.
0 = Power has not been reset since last read.
Indicates whether VCO autotuner selection was successful:
1 = Indicates successful automatic VCO selection.
0 = Ind i cates the autosel ect functi on i s d i sab l ed or autom ati c V C O sel ecti on w as unsuccessful .
Status indicator for the VCO autotuner function:
1 = Indicates the automatic VCO selection process is active.
0 = Indicates the automatic VCO selection process is inactive.
PLL lock detect:
1 = PLL is locked.
0 = PLL is unlocked.
Indicates DC offset correction accuracy:
1 = DC offset correction detected negative signal excursions in either the I or Q channel.
0 = No signal excursions detected.
Indicates DC offset correction accuracy:
1 = DC offset correction detected positive signal excursions in either the I or Q channel.
0 = No signal excursions detected.
Reserved.
Indicates whether the signal level is above or below the programmed attack-point
threshold:
1 = Signal is above the programmed attack-point threshold.
0 = Signal is below the programmed attack-point threshold.
Indicates which VCO was selected by the VCO autotuner.
Indicates which VCO sub-band was selected by the VCO autotuner.
Provides a 3-bit digital reading of the VCO tuning voltage.
