I'm trying to write a short code for TC1796 CPU but I've faced an issue. 
When I use the following assembler code everything works fine:

call 0x800xxxxx
ret

But the following code does not work and I have no clue why:
movh.a a15, #High
lea a15, [a15]Low
nop // tried without this instruction also
calli a15 // crushed
ret

I hope that Infineon engineers can shed light on this problem. When I replace calli to call(only this single instruction) the code works just fine. So I believe the problem with "CALLI" instruction. 

   Hello, I need your help. Thank you very much
   It is normal for the program to jump from the boot area to the app area, but after jumping from the app area to the boot area, the program in the app area does not run normally, and it is looping in one place. The program keeps looping at 0x00C00090.
    Now it is certain that the jump instruction is no problem, the program has jumped to the boot area, before jumping I have closed the interrupt. Or provide some code about software reset, I tried software reset, but it failed, maybe my instructions are not correct.

Hello,

i know this is not the correct forum. But i have not found a more suitable one.

I would like to know the difference between the types CY90F543GPFR-GE1 and CY90F543GPF-GE1. I could not find the meaning of "R" in the designation so far. 

I don't think it has anything to do with the packaging, as both parts are delivered in the tray.

Thank you very much for your help.

Hello,

We are currently using an FMx family of microcontrollers, and we are using files provided by Infineon (including the former Cypress).

These include the source code and header files (xxx.c, xxx.h, xxx.inc) of the "microcontroller I/O register declaration file" and "I/O register macro declaration file".

Am I correct in understanding that these do not fall under FOSS (Free Open Source Software)?

Hello all,

for a couple of months now we are experiencing sporadic PLL synchronization losses during our temperature test campaigns. Before that, the same product seemed to work fine during the tests. We don't have any hint about a change in the hardware or in the test test setup which could cause the sudden problems.

One assumption is that there could be an EMI problem. But there is no explanation why we had no problems before.

Does anyone know about the PLL being so sensitive under certain conditions?

The PLL setup seems sound and in spec. But is it possible that certain settings are more robust than others?

Would be glad to get new ideas, since we are running out of them now.

Hello,

FM4(S6E2H16G0AGV20000)のクロックギアを使用して、
低周波から高周波へ徐々にシフトさせて、電源電流の変動を抑えたいと考えております。
以下のPeripheral Manualは確認しております。
https://www.infineon.com/dgdl/Infineon-32-BIT_MICROCONTROLLER_FM4_PERIPHERAL_MANUAL-UserManual-v06_00-JA.pdf?fileId=8ac78c8c7d0d8da4017d0f9117267e56

クロックギアを使用して低周波から高周波に切り替える際に、かかる時間の計算方法を教えてください。
（メインPLLクロックの64クロック×ループ数×ステップ数であってますか）

また、もしクロックギアを使わずに、急激に周波数を変化させた場合、変動する電源電流の大きさはどのくらいでしょうか。
（周波数の変化幅と、電流の変化量に相関関係があるのでしょうか）

I would like to use the clock gear of FM4 (S6E2H16G0AGV20000) to gradually shift from low frequency to high frequency to suppress fluctuations in power supply current.
The following Peripheral Manual has been confirmed.
https://www.infineon.com/dgdl/Infineon-FM4_Family_Peripheral_Manual_Main_Part_(TRM)-UserManual-v06_00-EN.pdf?fileId=8ac78c8c7d0d8da4017d0f911bce7e60

How do you calculate the time it takes to switch from low to high frequency using clock gear?
(Is it 64 clocks of the main PLL clock x number of loops x number of steps?)

Also, if you suddenly change the frequency without using a clock gear, how much will the power supply current fluctuate?
(Is there a correlation between the width of the frequency change and the amount of current change?)

Hello! We are pursuing the replacement of an XE167F96F80LACFXUMA1C with an XC228796F80LACKXUMA1 as per previous PCN guidelines. Would I assume immediately that the appropriate compiler for the latter must be used to compile present code with the latter part number IC as the target? Is there any information downloadable about compatibility?
