TDA4VM-Q1: The relationship between the value in ESM_RAW and the interrupt ID

Annie Liu

Part Number: TDA4VM-Q1

Hi Team,

This is the value of the register that the current software reads MCU_ESM ESM_RAW. 

Value in WKUP_ESM ESM_RAW register

The customer wants to know why the value 0x0000 0007 at 0x4080 0400 is generated.

He doesn't find a direct description in the manual. Is it related to the Intterup map described below?

Would you help to share your analysis?

Thanks,

Annie

    Please be aware the SDL (Software Diagnostics Library) has examples on how to use the ESM module.

    Regarding the address 0x4080 0000, TRM shows this as Config Error Raw Status/Set Register

    For MCU_ESM0_CFG instance 0.  Following the register description Q = N * 32 + Bit. group N, is 0, and has bits 0,1,2 set.

    The register description includes a link to the following section in the TRM, is available, which provides additional information and indicates to check the Interrupt Sources in Section 9.

    From the ESM Interrupt Sources, n=0, would correspond to the MCU_PLLFRAC2_SSMOD0_LOCKLOSS_IPCFG_0, as has been pasted above in the original post.

    This aligns with the SDL 1.0 code, search on "SDLR_MCU_ESM0_ESM_LVL_EVENT_MCU_PLLFRAC2_SSMOD0_LOCKLOSS_IPCFG_0", and see the test code in sdl/test/j7_clock/main.h.
