the IREFSTEN bit. For the ICS to run in stop, the LVDE and LVDSE bits in the SPMSC1 must both be
set before entering stop.
3.6.1
Active BDM Enabled in Stop Mode
Entry into active background mode from run mode is enabled if the ENBDM bit in BDCSCR is set. This
register is described in the Development Support chapter of this data sheet. If ENBDM is set when the CPU
executes a STOP instruction, the system clocks to the background debug logic remain active when the
MCU enters stop mode so background debug communication is still possible. In addition, the voltage
regulator does not enter its low-power standby state; it maintains full internal regulation.
Most background commands are not available in stop mode. The memory-access-with-status commands
do not allow memory access, but they report an error indicating that the MCU is in either stop or wait
mode. The BACKGROUND command can be used to wake the MCU from stop and enter active
background mode if the ENBDM bit is set. After active background mode is entered, all background
commands are available.
Table 3-3 summarizes the behavior of the MCU in stop when entry into the active background mode is
enabled.
3.6.2
LVD Enabled in Stop Mode
The LVD system is capable of generating either an interrupt or a reset when the supply voltage drops below
the LVD voltage. If the LVD is enabled in stop (LVDE and LVDSE bits in SPMSC1 both set) at the time
the CPU executes a STOP instruction, the voltage regulator remains active.
Table 3-4 summarizes the behavior of the MCU in stop when LVD reset is enabled.
