BIT 7
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.
BIT 6
SOFT FETG:
0 = (Default)
1 = Forces the bias and modulation outputs to their off state and assert the FETG output.
BIT 5
RESERVED (Default = 0)
BIT 4
TX-F RESET:
0 = (Default)
1 = Resets the latch for the TX-F output. This bit is self-clearing after resetting TX-F.
BIT 3
SOFT TX-D: This bit allows a software control that is identical to the TX-D pin. See the BIAS and
MOD Output as a Function of Transmit Disable (TX-D) section 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 the external TX-D pin.
1 = Internal TX-D signal is high.
BIT 2
TX-F STATUS: Reflects the active state of the TX-F pin.
0 = TX-F pin is not active.
1 = TX-F pin is active.
BIT 1
LOS STATUS: Loss of Signal. Reflects the logic level of the LOSI input pin.
0 = LOSI is logic-low.
1 = LOSI is logic-high.
BIT 0
RDBY: Ready Bar.
0 = VCC is above POA.
1 = VCC is below POA and/or too low to communicate over the I2C bus.
