• ICS_C1[IREFS] bit is written to 0
• BDM mode is not active and ICS_C2[LP] bit is written to 1
In FLL bypassed external low power mode, the ICSOUT clock is derived from the
external reference clock source and the FLL is disabled. The ICSLCLK will be not
available for BDC communications. The external reference clock source is enabled.
8.2.2.7 Stop (STOP)
In stop mode, the FLL is disabled and the internal clock source can be enabled or
disabled. The BDC clock is not available and the ICS does not provide MCU clock
source.
Stop mode is entered whenever the MCU enters a stop state. In this mode, all ICS clock
signals are static except in the following cases:
• ICSIRCLK will be active in stop mode when all of the following conditions occur:
• ICS_C1[IRCLKEN] bit is written to 1
• ICS_C1[IREFSTEN] bit is written to 1
• OSCOUT will be active in stop mode when all of the following conditions occur:
• ICS_OSCSC[OSCEN] bit is written to 1
• ICS_OSCSC[OSCSTEN] bit is written to 1
NOTE
The DCO frequency changes from the pre-stop value to its reset
value and the FLL need to re-acquire the lock before the
frequency is stable. Timing sensitive operations must wait for
the FLL acquisition time, t

, before executing.
