5.11 WAKE-UP / INTERRUPT LINES MANAGEMENT UNIT (WUIMU)
5.11.1 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
(when available) 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 39. Wake-Up Lines / Interrupt Management Unit Block Diagram
Note 1: The reset signal on the Stop bit is stronger than the set signal.
