bit7
FETG STATUS: Reflects the active state of FETG. The FETG-DIR bit in Table 02h, Register 89h
defines the polarity of FETG.
0 = Normal operation. Bias and modulation outputs are enabled.
1 = The FETG output is active. Bias and modulation outputs are disabled.
bit6
SOFT FETG:
0 = (Default)
1 = Forces the bias and modulation outputs to their off states and asserts the FETG output.
bit5
RESERVED (Default = 0)
bit4
TX-F RESET:
0 = Does not affect the TX-F output. (Default)
1 = Resets the latch for the TX-F output. This bit is self-clearing after the reset.
bit3
SOFT TX-D: This bit allows a software control is identical to the TX-D pin. See the section on TX-D for
further information. Its value is wired-ORed with the logic value of the TX-D pin.
0 = Internal TX-D signal is equal to external TX-D pin.
1 = Internal TX-D signal is high.
bit2
TX-F STATUS: Reflects the active state of TX-F.
0 = TX-F pin is not active.
1 = TX-F pin is active.
bit1
LOS STATUS: Loss of Signal. Reflects the logic level of the D0 input pin. Note that with the use of the
MUX LOSI and INV LOSI bits (Table 02h, Register C0h), the D0 pin is controlled by the LOSI pin.
0 = D0 is logic-low.
1 = D0 is logic-high.
bit0
RDYB: Ready Bar.
0 = VCC is above POA.
1 = VCC is below POA or too low to communicate over the I2C bus.
