MAX3107 ISR and IRQ

Thread Summary

The user inquired about the behavior of the MAX3107 regarding ISR setting and IRQ generation when bits in the LSR are still set, with all interrupts enabled in the LSRIntEn register and LSRErrlEn bit enabled in the IRQEn register. The final answer directed the user to visit the technical support pages on the newly integrated Analog Devices website for assistance with MAX3107 products, as only Maxim ATE products are currently supported on EngineerZone.

Product Number: MAX3107

would you inform me of the behaviour of MAX3107 for ISR setting and IRQ generation when some bits in LSR are still set.

All of interrupts are enabled in LSRIntEn register and LSRErrlEn bit is enabled in IRQEn register.

When IRQ is generated caused by LSRErrlEn  and  ISR is read and cleared , but LSR is NOT cleared, Is LSRErrlnt bit set again  and  IRQ generated again?
