Description
This API enables the 64 bit time stamp counter. The Time Stamp Counter (TSC) stops only upon Reset or powerdown. When time stamp counter is enabled (following a reset or powerdown of the CPU) it will initialize to 0 and begin incrementing once per CPU cycle. You cannot reset the time stamp counter.

============================================================================
CSL_tscRead

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();
