MSPM0L2228: IIDX Register seems not changed

Jerry Kuo

Part Number: MSPM0L2228

Tool/software:

Hi team,

My customer is using MSPM0L2228. They did one test as below and find out the IIDX Register seems not changed. Please help clarify if this scenario is normal. Thank you.

Test environment:

HW : LP-MSPM0L2228
SDK version: mspm0_sdk_2_02_00_05
CCS Theia version: 1.5.0.11
SW Example: i2c_target_rw_multibyte_fifo_interrupts_LP_MSPM0L2228_nortos_ticlang

Test result:

The DL_I2C_IIDX_TARGET_STOP state is always triggered in the code, and the LED on the board is blinking,

They find some registers (eg. SSR) keep changing. But the corresponding IIDX Register (Offset = 1020h) doesn't change (keep '0'). Is this reasonable ? Customer worry if CCS register window is trustable ?

Hi Jerry,

Firstly, click the bottom below to continuously observe the change of register status.

Secondly, the API DL_TimerG_getPendingInterrupt() will clear the (highest priority) pending interrupt status in the corresponding IIDX Register, so customer need to add a break point before this API to observe pending interrupt status, shown as below:

Hi Pengfei,

Where can I find the API DL_TimerG_getPendingInterrupt in this example? It doesn't seem to be in this example.
