Return Value
None

Pre Condition
None

Post Condition
Time Stamp Counter value starts incrementing

Writes
TSCL=0, TSCH=0

Example

        
        CSL_tscEnable ();
        
 *

Description
Reads the 64 bit timer stamp conter and return the 64-bit counter value.

Arguments None

Return Value CSL_Uint64

  • 64 Bit Time Stamp Counter value

Pre Condition
None

Post Condition
None

Reads TSCL, TSCH

Example

        CSL_Uint64        counterVal;
        
        ...
        
        CSL_tscStart();
        
        ...
        
        counterVal = CSL_tscRead();
        
 *
