D.8.4 MCCI Interrupt Vector Register
MIVR — MCCI Interrupt Vector Register
The MIVR determines which three vectors in the exception vector table are to be used for
MCCI interrupts. The SPI and both SCI interfaces have separate interrupt vectors
adjacent to one another. When initializing the MCCI, program INTV[7:2] so that INTV[7:0]
correspond to three of the user-defined vectors ($40–$FF). INTV[1:0] are determined by
the serial interface causing the interrupt, and are set by the MCCI.
At reset, MIVR is initialized to $0F, which corresponds to the uninitialized interrupt vector
in the exception table.
INTV[7:2] — Interrupt Vector
INTV[1:0] — Interrupt Vector Source
D.8.5 SPI Interrupt Level Register
ILSPI — SPI Interrupt Level Register
The ILSPI determines the priority level of interrupts requested by the SPI.

INTV[7:2] are the six high-order bits of the three MCCI interrupt vectors for the MCCI,
as programmed by the user.
INTV[1:0] are the two low-order bits of the three interrupt vectors for the MCCI. They
are automatically set by the MCCI to indicate the source of the interrupt. Refer to Table
D-41.
Writes to INTV0 and INTV1 have no meaning or effect. Reads of INTV0 and INTV1
return a value of one.
