Interrupt mapping
For full details on the interrupt controller see
ST40 System Architecture Manual Volume 1:System.
The mapping of the CPU interrupts is described in
Section 5.3.1, Section 5.3.2 and Section 5.3.3.
Note:
Some INTEVT codes are shown as reserved in Table 3 and therefore cannot be generated by this
device.
