Bit Field Value Description
31-4 Reserved 0 Reads return 0. Writes have no effect.
3-0 INVECT0 0-Fh Interrupt vector offset for INT0. This register indicates the offset for interrupt line INT0. A read to
this register updates its value to the next highest priority pending interrupt in SCIFLR and clears
the flag in SCIFLR corresponding to the offset that was read. See Table 30-1 for a list of the
interrupts.
Note: The flags for the receive (SCIFLR[9]) and the transmit (SCIFLR[8]) interrupt cannot be
cleared by reading the corresponding offset vector in this register (see detailed description
in SCIFLR register).
30.7.9 SCI Interrupt Vector Offset 1 (SCIINTVECT1)
