UART or any other interrupt dont have timeout, occurs immediately as source event condition meet.

Exist only priority when other interrupt do job, lower priority is delayed.

When the 1-byte interrupt initialization is complete. It takes a while before the interrupt occurs.

What is the "1-byte interrupt initialization"?

Interrupts are triggered within about 10 cycles of when they occur. There is no timeout setting that changes this.

Perhaps your code is busy elsewhere, or otherwise not doing what you expect.
