You can modify these priorities for the following program execution
levels individually in DX 0, by specifying the priority value from ’1’
to ’5’ (the value ’1’ means highest priority):
•• timed interrupts
•• system interrupt INT X (X = A, B, C or D),
•• system interrupt INT E,
•• system interrupt INT F,
•• system interrupt INT G.
Example
Assignment of priorities for interrupt servicing
"system interrupts":
System interrupt INT A/B/C/D
level priority 1
Timed interrupts level priority 2 descending
System interrupt INT E level priority 3 priority
System interrupt INT F level priority 4
System interrupt INT G level priority 5
