5.12 WAKE-UP / INTERRUPT LINES MANAGEMENT UNIT (WUIMU)
5.12.1 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).
The 16 additional external Wake-up/interrupt pins
can be programmed as external interrupt lines or
as wake-up lines, able to exit the microcontroller
from low power mode (STOP mode) (see
55).

Note 1: The reset signal on the Stop bit is stronger than the set signal.
