66     Trimble ThunderBolt E GPS Disciplined Clock User Guide

This command packet causes the current configuration settings for the specified user 
segment (or all segments) to be written to NVS. The segment ID is contained in a data 
byte.

This command packet sets the PPS driver switch to one of the values listed below. The 
current driver switch value can be requested by sending the packet with no data bytes 
except the subcode byte.

Driver switch values 3 and 4 only make sense in Over-Determined Timing mode. In any 
position fix mode the effective choices are always on or during fixes which you get if 
you set the driver switch to 3 or 4.

ThunderBolt E can also be configured to generate an Even Second pulse in place of the 
PPS pulse by setting the value as shown in the table below.
