interrupt priority (VIM)

The vectored interrupt module (VIM) provides a fully programmable priority scheme. Interrupt requests origi-

nating from the PLF111 peripheral modules (i.e., SPI; LIN1 or LIN2; RTI; etc.) are assigned to channels within

the 32-channel VIM where, via programmable register mapping, the interrupt priority of the channels can be

changed. Programming multiple interrupt sources to the same VIM channel effectively shares the VIM channel

between sources.

The VIM request channels are maskable so that individual channels can be selectively disabled. All interrupt

requests can be programmed in the VIM to be of either type:

Fast interrupt request (FIQ)

Normal interrupt request (IRQ)

The VIM prioritizes interrupts. The precedences of request channels decrease with ascending channel order

in the VIM (0 [highest] and 31 [lowest] priority). For VIM default mapping, channel priorities, and their associated

modules, see Table 6, Interrupt Priority (VIM).
