Interrupt Base Register — INTBASE
The Interrupt Base Register indicates the beginning of the Interrupt Service Routine
(ISR) memory range that contains the interrupt service routines for up to 128 sources.
The starting address must be on a boundary equal to the granularity of the ISR
memory range as specified by the INTSIZE registers.
For instance, the upper 23 bits are used for a 512 Byte ISR memory range, and the
upper 16 bits for a 64 KByte ISR memory range., etc.
