Reset Generation (I/O pin 3 - RESET)
The power-on-reset for the FTS250 is generated on-board. If it is desired to extend the power-on-reset signal or provide a manual
reset of the GPS receiver, pull this signal low.

* Note: Holdover is not supported in this mode; loss of the 10MHz reference will rail the
PLL output until the reference returns or another mode is selected.
