[Alexander]

Hi All,

I've tried to figured out how to software the pin XRES but without successful.

There any options how can to software the XRES so i can do reset to PSOC without external intervention?

Thanks for any help.

Hi,

I wonder if "CySoftwareReset()" can be used for your purpose.

Hi,

I've seen this function in several posts but couldn't find in datasheets where it exists to understand how to use it.

can you please refer where can I find information about this function? which type of variable Is it?

thanks for your reply.

Hi,

Assuming that you are using PSoC Creator,

CySoftwareReset() is defined in CyLib.c as below.

You can also directly set that bit using

CY_LIB_RESET_CR2_REG |= CY_LIB_RESET_CR2_RESET ;

For the meaning of the bit and register, 

please refer to PSoC 5LP Register TRM

Found if now.

I'm programing the the project into the chip and I have code in Visual Studio, how can I use this function when I need to do reset to PSOC?

isr_1 can help me with it?

Thanks for your help.

Hi, 

I tried with my CY8CKIT-059 (CY8C5888LTI-LP097).

Hopefully C source should be usable for your board/device, too.

Hi, 
thanks so much.
little question - can you please explain when does the function CY_ISR is execute? 

Thanks!

Alexander,

CY_ISR gets executed when the SW gets pressed.
