ST7DALIF2

Important notes

167/171

The symptom does not occur when the interrupts are handled normally, i.e. when:

●

The interrupt request is cleared (flag reset or interrupt mask) within its own interrupt

routine

●

The interrupt request is cleared (flag reset or interrupt mask) within any interrupt

routine

●

The interrupt request is cleared (flag reset or interrupt mask) in any part of the code

while this interrupt is disabled

If these conditions are not met, the symptom can be avoided by implementing the following

sequence:

Perform SIM and RIM operation before and after resetting an active interrupt request

Ex:

SIM

reset flag or interrupt mask

RIM

23.6

Using PB4 as external interrupt

PB4 cannot be used as an external interrupt in Halt mode because the port pin PB4 is not

active in this mode.

23.7

Timebase 2 interrupt in Slow mode

Timebase 2 interrupt is not available in slow mode.
