4.17.3 Clock Source Options

The RTI module uses the RTI1CLK clock domain for generating the RTI time bases.

The application can select the clock source for the RTI1CLK by configuring the RCLKSRC register in the

System module at address 0xFFFFFF50. The default source for RTI1CLK is VCLK.

For more information on clock sources refer to Table 4-8 and Table 4-13.

4.17.4 Network Time Synchronization Inputs

The RTI module supports 4 Network Time Unit (NTU) inputs that signal internal system events, and which

can be used to synchronize the time base used by the RTI module. On this device, these NTU inputs are

connected as shown below.
