← TechnologyWhich consequence results when exceeding the maximum interrupt latency in a microcontroller's timer circuit?
A)Data loss from buffer overrun✓
B)Increased electromagnetic interference (EMI)
C)Permanent silicon transistor degradation
D)Accelerated oscillator frequency drift
💡 Explanation
Data loss occurs due to a missed interrupt servicing the timer circuit, because the input data buffer overflows before it can be processed by the interrupt handler through interrupt stacking. Therefore, buffer data is lost, rather than EMI increases or transistor degradation.
