Hello ,

TC375 hard reset when TLF35584 after send SPI command (for standby) 

spi_transfer(0x15, 0xEC);

spi_transfer(0x16, 0x13);

Hard reset is expected behaviour ?

and 

after hard reset  STM timer is going to be not suspended. when hit the breakpoint timer is not going to suspended.

I observe a SMU ALM7[26] while executing Bootmanger in Core-0 from Pflash-0, before jumping to application software i am able to clear this alarm by writing into MBAB bit of FlashCon register(CPU1_FLASHCON2.B.MBABCLR).

But once Bootmanger gives a jump to start address of application software this bit ALM7[26] is SET AGAIN. I could not understand two things:
1. Why and how this bit is set even after i am clearing it?
2. Who is setting this bit again if there is only a jump routine performed between clearing this bit and jumping to application?

Can someone help me understand this behavior and steps to fix /resolve this. Thanks.

Hello Infineon support,

I am trying to send my ECU to sleep mode using TLF35584 and TC399. 

As you can see in the screenshot, the ECU starts to go to sleep (ROT set LOW) but the STB_N is back to high which inhibits the ECU to continue going to sleep and forces it back to Normal mode.

I had some doubts about the pin configuration (STB_N is initially an output from the microcontroller). For that, I even changed the pin direction (INPUT with pull down) before settting the TLF to sleep mode. Unfortunately, this was not sufficient. 

After some analysis, it seems that the microcontroller TC399 sets this PIN back to HIGH during reset. 

Any idea what could be the reason for the STB to be back HIGH and the same time ROT goes to LOW?

Hello, I am working on TC399 - ASCLIN module.

Need help/clarification about CE (Collision Detection Error) flag. [User manual part 2, v2.0.0, p36-75]

What my understanding is, collision occurs when more than one LIN slaves tries to respond to same frame on the LIN bus.

Is my understanding is correct?

Can anyone elaborate the part of description in user manual for CE flag. "When transmitting, signals if the transmitted data differs from the received data." ?

Thank you.
