ADDENDUM TO SECTION 9: INTERRUPTS

Unless marked, all flags must be cleared by the application software.

Cleared automatically by hardware when the service routine is entered.

If edge-triggered, the flag is cleared automatically by hardware when the service routine is entered. If level-triggered, the flag follows the state of the interrupt pin.

The global 1-Wire interrupt enable bit (EOWMI) and individual 1-Wire interrupt source enables are located in the internal 1-Wire registers and must be accessed by the

OWMAD and OWMDR SFRs. Individual 1-Wire interrupt source flag bits located in the internal 1-Wire bus master interrupt flag register are accessed in the same way.
