STM8 SWIM pin as output/Debug

1. I have STM8S003F3 & want to use its debug pin as output. 

So I will configure it my code.

2. Will that make debug option dead?

On next power up, will I be able to debug the code?? Because pin will already be configured as output by that time

Yes, you can use SWIM pin as output, it won't brick the device.

Hi

I am answer this from memory, and bear in mind that I work with the STM32 but I have written the driver for the STM32 to program a STM8 with SWIM ''

2. Will that make debug option dead?

On next power up, will I be able to debug the code?? Because pin will already be configured as output by that time

'' Yes and No. If the debug is done with SWIM - it will toggle the reset line on SWIM entry. If the line is in use for SWIM - it CANNOT be used for output (ie it is held by the SWIM interface). The simple answer is : if you debug - you cannot use the Pin for output. If you do not debug - the pin will be configures for output
