Features Supported

API to enable/disable a module clock
API to set clock frequency for module
Generic utility API like get CPU clock, get core name string, control module MMR lock/unlock API
API's to configure all the SOC and Time Sync XBAR's

SysConfig Features

Note: It is strongly recommend to use SysConfig where it is available instead of using direct SW API calls. This will help simplify the SW application and also catch common mistakes early in the development cycle.

SOC driver is integrated with each of the drivers. User need not perform any explicit configuration for this driver
The Input for every XBAR output instance can be configured through SysConfig (Input-Signals going into the XBAR, Instance-Each output signal from the XBAR)
Refer to the following examples on how to configure XBAR through SysConfig - EPWM HR duty cycle, ECAP APWM mode, EQEP frequency measurement
XBAR outputs routed to other XBAR's get automatically configured when input is selected for the end XBAR

Sample XBAR Configuration

XBAR configuration also possible from the SysConfig module to which it is connected. For example, DMA Trigger XBAR can be configured from EDMA module.

NA

Most of these APIs are already integrated with SysConfig tool and the generated code does the required call to enable a module, set the required clock and so on. User need to use these APIs in their application only for exceptional scenarios.

Include the below file to access the APIs

#include <drivers/soc.h>

Get Core Name String

    const char *coreName;
 
    coreName = SOC_getCoreName(CSL_CORE_ID_R5FSS0_0);
    DebugP_log("Core name is: %s\r\n", coreName);

Get CPU Clock Frequency

    uint64_t cpuClockRate;
 
    cpuClockRate = SOC_getSelfCpuClk();
    DebugP_log("CPU Clock Frequency: %u\r\n", cpuClockRate);
