16.6 Low-Power Modes
The WAIT and STOP instructions put the MCU in low-power-
consumption standby modes.
16.6.1 Wait Mode
If enabled, the break module is active in wait mode. In the break routine,
the user can subtract one from the return address on the stack if SBSW
is set
). Clear the SBSW bit by writing logic
zero to it.
16.6.2 Stop Mode
A break interrupt causes exit from stop mode and sets the SBSW bit in
the break status register. See
