conditions. The selected mode is entered following the execution of a STOP instruction.
3.6.1
Stop3 mode is entered by executing a STOP instruction under the conditions as shown in
states of all of the internal registers and logic, RAM contents, and I/O pin states are maintained.
Stop3 can be exited by asserting RESET, or by an interrupt from one of the following sources: the real-time
counter (RTC), LVD system, ACMP, ADC, SCI or any pin interrupts.
If stop3 is exited by means of the RESET pin, then the MCU is reset and operation will resume after taking
the reset vector. Exit by means of one of the internal interrupt sources results in the MCU taking the
appropriate interrupt vector.
3.6.1.1
The LVD system is capable of generating either an interrupt or a reset when the supply voltage drops below
the LVD voltage. For configuring the LVD system for interrupt or reset, refer to
Detect (LVD)
time the CPU executes a STOP instruction, then the voltage regulator remains active during stop mode.
For the ADC to operate in stop mode, the LVD must be enabled when entering stop3.
For the ACMP to operate in stop mode with compare to internal bandgap option, the LVD must be enabled
when entering stop3.
3.6.1.2
Entry into the active background mode from run mode is enabled if ENBDM in BDCSCR is set. This
register is described in
STOP instruction, the system clocks to the background debug logic remain active when the MCU enters
stop mode. Because of this, background debug communication remains possible. In addition, the voltage
regulator does not enter its low-power standby state but maintains full internal regulation.
