3.12 WAKE-UP / INTERRUPT LINES MANAGEMENT UNIT (WUIMU)
3.12.1 Introduction
The Wake-up/Interrupt Management Unit extends
the number of external interrupt lines from 8 to 23
(depending on the number of external interrupt
lines mapped on external pins of the device). It al-
lows the source of the INTD1 external interrupt
channel to be selected between the INT7 pin and
up to 16 additional external Wake-up/interrupt
pins.
These 16 WKUP pins can be programmed as ex-
ternal interrupt lines or as wake-up lines, able to
exit the microcontroller from low power mode
(STOP mode) (see
Figure 30. Wake-Up Lines / Interrupt Management Unit Block Diagram

Note: Reset Signal
on stop bit is
stronger than
the set signal
