REMARK: the Interrupt priority must be fixed ad the
beginning of the main program, because at the
RESET REG_CONF1=’00000000’, and this
condition could generate wrong operations.
During the program execution it is possible to
modify the interrupt priority only with the following
procedure:
step 1):
mask the interrupts by means of a UDGI (or
MDGI) instruction
step 2):
change the REG_CONF1 value to modify the
interrupt priority
step 3):
reset by mean of RINT instructions all the
pending interrupt routines
step 4):
unmask the interrupts by mean of a UEGI (or
MEGI) instruction
When a source provides an Interrupt request, and
the request processing is also enabled, the CU
changes the normal sequential flow of a program
by transferring program control to a selected
service routine.

Table 4.4. RINT instruction code
When an interrupt occurs the CU executes a JUMP
instruction to the address loaded in the related
location of the Interrupt Vector.
When the execution returns to the original
program, it begins immediately following the
interrupted instruction.
4.6 Interrupts and Low power mode
All interrupts allow the processor to leave the WAIT
low power mode. Only the external Interrupt, when
enabled, allows the processor to leave the HALT
low power mode when it is not masked.
4.7 Interrupt RESET
An eventually pending interrupt can be reset with
the instruction RINT j, which resets the interrupt
j-th where j identify the peripherals as described in
the following table. (see table 4.4).
The assembler instruction:
RINT 2
Resets the PWM/Timer 1 interrupt.
REMARK: RINT command must be preceded
from a UDGI (or MDGI) command and followed
by a UEGI (or MEGI) command.
