What can cause variable value reset, if you take into consideration that UART and TIMER interrupts are used and IAP? My variables which are stored in internal RAM got reset.

Wrong IAP usage?

32.3.2.8 RAM used by IAP command handler
Flash programming commands use the top 32 bytes of on-chip RAM. The maximum stack
usage in the user allocated stack space is 128 bytes and it grows downwards.


But it's difficult to guess what you are doing in detail
