WebbWhen any interrupt routine is executed then I bit of SREG is cleared to avoid next interrupt execution. The bit is reset by RETI.I.e. you can do it also manually SBI SREG,I (or via uint8_t sreg = SREG; sreg = _BV(I); SREG = sreg;).. But also USART_RXC_vect may be called again! I don't like any _delay() in interrupt routines as it must be as short as possible.
