Reset Overview
In the configuration described in the preceding figure, FTM modules A and B have their
FTM counters enabled if at least one of the gtb_out signals from one of the FTM modules
is 1. There are several possible configurations for the interconnection of the gtb_in and
gtb_out signals (represented by the example glue logic shown in the figure). Note that
these configurations are chip-dependent and implemented outside of the FTM modules.
See the Chip Configuration details for the chip's specific implementation.
36.4.28.1 Enabling the global time base (GTB)
To enable the GTB feature, follow these steps for each participating FTM module:
To initiate the GTB feature, follow these steps for the FTM module used as the time base:
36.5 Reset Overview
The FTM is reset whenever any chip reset occurs.

counters may lose synchronization during FTM operation.
The GTB feature only allows the FTM counters to start
their operation synchronously.
