How to declare RAM variable as volatile in STM8 assembly language

Hi All,I want to know how i can declare any RAM variable as volatile in STM8 assembly language. I have one variable, which is shared between ISR and main function. It is causing issue during updates, when the software is in free run mode.Can anyone t...

Regarding POR.The input voltage drops to higher than 0V, and then rises again. Can STM8 work normally in this case?

The input voltage drops to between 0V and VIT- （Brown-out reset threshold） , such as 2V，and then rises higher than VIT+ （Power-on reset threshold）again. Can STM8 work normally in this case?

DIFERENCE BETWEEN THESE 2 BECAUSE THE SECND ONE DOESN'T WORKS M48T08-100PC1

Dear all,good evening.Kindly inform us for the diferrences between these 2 timekeeper Ram M48T08-100PC1 (find attached photos).The first one with the codes 1) H990E9849, HT3598X on it works properly on the P.C.B. card instead the other with the codes...

Need to write and read reliably to a protected block of EEPROM memory from startup to startup

Hi. I'm using an STM8 MCU. I'd like to reliably write to and read from a block of EEPROM/FLASH memory (about 1k) that will never be overwritten either by the MCU or by programming/debugging via SWIM, but can be read and written from code. I'm writ...

Hi, please kindly help to confirm ECMF02-2AMX6 that what is Cdiode spec. Thanks.

Problem CAN_ReceiveAll in standard peripheral library

I develop stm8 using cosmic compiler and v.2.3.1 standard libary.I think there is a problem with the definition of CAN_ReceiveAll.In this function I can get an address of _Data variable.But, I can not get the address in Caller side.My thoughts should...
