ERAD

Table of Contents

The ERAD IP in the F29 devices is an enhanced version of the IP present in F28 devices. Some of the key differences include :

  • Separate ownership configuration for individual submodules
  • Support for 64 bit compares (for data bus)
  • Support for Min and Max counts (F28 ERAD only supported max count)
  • HWBP is renamed to EBC. CTM is renamed to SEC
  • All the submodules registers are combined into a single registerfile. The EBC and SEC registers are available as registerfile arrays. Hence the indexing starts from 0, instead of 1 which was used in F28.
  • Reset value of SEC{#}.REF is 0xFFFFFFFF, while it is 0 in F28. Setting REF to 0 would cause counter match event to happen by default.
Note
CCS uses ERAD module for inserting all the hardware breakpoints in an F29 device. In C28 based devices, the first 2 HWBPs are implemented using the bus comparator modules present in the C28 CPU itself. The remaining HWBPs are implemented using the bus comparator in ERAD. In case of C29 based devices, all the HWBPs are implemented using ERAD. In order to avoid conflicts between application and debugger, it is recommended for application to start from EBC7.

Macro and enum mapping

Base address macros available in F28 devices :

  • ERAD_GLOBAL_BASE
  • ERAD_HWBP1_BASE - ERAD_HWBP8_BASE
  • ERAD_COUNTER1_BASE - ERAD_COUNTER4_BASE
  • ERAD_CRC_GLOBAL_BASE
  • ERAD_CRC1_BASE - ERAD_CRC8_BASE
  • ERAD_PCTRACE_BASE

In F29 devices, a single macro ERAD_BASE is provided. All the driverlib functions which expects the submodule base address as parameter has been updated to take in an enum as parameter instead. Refer to the Driverlib API mapping table for more details.

Note
The values of most of macros and enums are updated in the revised ERAD IP. In case hardcoded values were used instead of these macros/enums, please refer to the device TRM or switch to these macros/enums.

Differences in structs

  • ERAD_BusComp_Config
    • mask : 64-bit instead of 32-bit
    • reference : 64-bit instead of 32-bit
    • Additional configurations available. Please refer to the API guide for more details
  • ERAD_Profile_Params
    • busComp_base1 : renamed to busComp_instance1 and expects an enum of type ERAD_BusCompInstance instead of base address
    • busComp_base2 : renamed to busComp_instance2 and expects an enum of type ERAD_BusCompInstance instead of base address
    • counter_base : renamed to counter_instance and expects an enum of type ERAD_CounterInstance instead of base address
  • ERAD_Counter_Config
    • Additional configurations available. Please refer to the API guide for more details

Driverlib API mapping
