The interrupt model for the 1-Wire module allows interrupt service routines to drive continuations of operations, whether reading the results or processing more bytes. Most command sequences are small, so the module supports transactions of one, two, three, and four bytes at once. Because most commands start with a line reset, the operational model allows for a reset followed by the transaction, with an interrupt occurring when the transaction is complete. There is also support for enabling interrupts for reset complete (RST), no answer-to-reset (NOATR) and line-hold-low error detected (STUCK) in the 1-Wire Interrupt Mask (ONEWIREIM) register.
