4.5 Interrupt Sources and Vector Addresses
The interrupt modified vector register (IMVR) is an eight-bit register in which the six low bits
(bits 5 to 0) hold a hardware-generated code identifying an interrupt source, as listed in table 4.2.
The two high bits (bits 7 and 6) can be set to arbitrary values by the MPU.
