Bit Field Value Description
31-5 Reserved 0 Read returns 0. Writes have no effect.
4-0 INVECT0 0-1Fh 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 28-4 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).
28.7.10 SCI Interrupt Vector Offset 1 (SCIINTVECT1)
Figure 28-37 and Table 28-22 illustrate this register.

4-0 INVECT1 0-1Fh Interrupt vector offset for INT1. This register indicates the offset for interrupt line INT1. A read to
this register updates its value to the next highest priority pending interrupt in SCIFLR and clears

interrupts.
