My ISR is executed only once even if I attempt to clear the Timer Flag

WebMay 5, 2024 · TOV1 is automatically cleared when the Timer/Counter1 Overflow Interrupt Vector is executed. Alternatively, TOV1 can be cleared by writing a logic one to its bit location. Since you have ISR, even it's empty, it's should clear TOV. I would use a variable (volatile) as a flag, and set it inside ISR.

WebTimer: clearing update event flag can cause flagless input capture interrupt. The goal is to measure durations between input captures that exceed the 16 bit counter range by adding counter overflows. There appears to be no way to cleanly do this. The basic problem is that clearing the update-event interrupt flag is a read-modify register-write ...

WebJan 31, 2006 · The operation "TFLG1 = 0x01" would set TFLG1 to (0x03 0x01), which is 0x03. Writing that 0x03 will then reset *both* timer flags.
