Description
50
All reserved interrupt vectors should point to default or error
interrupt handlers.
10.5
Nested NMI interrupts are always enabled. Nested
maskable interrupts are disabled by default, however an in-
terrupt handler can allow nested maskable interrupts by set-
ting the I bit in the PSR. The LPR instruction is used to set
the I bit.
Nesting of specific maskable interrupts can be allowed by
disabling interrupts from sources for which nesting is not al-
lowed, before setting the I bit. Individual maskable interrupt
sources can be disabled using the IENAM0 and IENAM1
registers.
Any number of levels of nested interrupts are allowed, limit-
ed only by the available memory for the interrupt stack.
