Low Priority Register (INT_PRL_L)
Configuration Register 4 (04h) Read/Write
Reset Value: 1000 1000 (088h)
These three register are used to configure the
priority level of each interrupt source. The 24 bits
of these registers (PRL24-PRL0) are divided into 8
groups of three bits: each group is associated with
a priority level (from level 1, the highest, to level 8,
the lowest: level 0 is fixed for the NMI that can be
interrupted only by the TRAP) . The three bits of
each group are written with the code number
associated with the interrupt source (see Table
5.1).
PRL2-PRL1
: Interrupt priority level 1 (highest)
PRL5-PRL3
: Interrupt priority level 2
PRL8-PRL6
: Interrupt priority level 3
PRL11-PRL9
:Interrupt priority level 4
PRL14-PRL12
: Interrupt priority level 5
PRL17-PRL15
: Interrupt priority level 6
PRL20-PRL18
: Interrupt prioritylevel 7
PRL23-PRL21
: Interrupt priority level 8 (lowest)
Example: writing the code 110 into PRL8-PRL6
bits the priority level 3 is assigned to the Port A
Interrupt.
Warning:
the Priority Level configuration registers
must be always configured.
