FETG DIR: Chooses the direction or polarity of the FETG output for normal operation.
0 = (Default) Under normal operation, FETG is pulled low. Intended for use with nMOS.
1 = Under normal operation, FETG is pulled high. Intended for use with pMOS.
TX-F EN: The TX-F output pin always reflects the wired-OR of all TXF enabled alarm states. This bit
will enable the latching of the alarm state for the TXF output pin.
0 = (Default) Not latched.
1 = The alarm bits are latched until cleared by a TX-D transition or power-down. If V
enabled for either FETG or TX-F then latching is disabled until the after the first V
made above the V
