Tell me can we use any function inside isr?..

Answer / Satendra Pal Singh Chauhan

"Yes, it's possible to call functions within an Interrupt Service Routine (ISR), but it's generally discouraged because ISRs are executed in interrupt context and must be as fast and deterministic as possible. In-line function calls can add significant overhead due to code generation and stack management."
