Work arounds
Work around 1: For Assembly Language
Source Code
The user may disable interrupt nesting, disable
interrupts before modifying the Interrupt 1 set-
ting or execute a DISI instruction before modi-
fying the CPU IPL or Interrupt 1. A minimum
DISI value of 4 is required if the DISI instruction
is executed immediately before the CPU IPL or
Interrupt 1 is modified, as shown in Example 13.
It is necessary to have DISI active for four cycles
after the CPU IPL or Interrupt 1 is modified.
operations:
-
-
-
-
cycles after any of the operations listed above.
CPU IPL is raised to Interrupt 1 IPL
level or higher, or
Interrupt 1 IPL is lowered to CPU IPL
level or lower, or
Interrupt 1 is disabled (Interrupt 1 IE
bit set to ‘0’), or
Interrupt 1 flag is cleared

Work around 2: For C Language Source Code
For applications using the C language, MPLAB
C30 versions 1.32 and higher provide several
macros for modifying the CPU IPL. The
SET_CPU_IPL macro provides the ability to
safely modify the CPU IPL, as shown in
Example 14.
There is one level of DISI, so this macro saves
and restores the DISI state. For temporarily
modifying and restoring the CPU IPL, the mac-
ros
RESTORE_CPU_IPL can be used, as shown in
Example 15. These macros also make use of
the SET_CPU_IPL macro.
