MSCAN08 Controller (MSCAN08)
21.9 Low Power Modes
Advance Information
360
In addition to normal mode, the MSCAN08 has three modes with
reduced power consumption: Sleep, Soft Reset and Power Down
modes. In Sleep and Soft Reset mode, power consumption is reduced
by stopping all clocks except those to access the registers. In Power
Down mode, all clocks are stopped and no power is consumed.
The WAIT and STOP instructions put the MCU in low power
consumption stand-by modes. summarizes the combinations of
MSCAN08 and CPU modes. A particular combination of modes is
entered for the given settings of the bits SLPAK and SFTRES. For all
modes, an MSCAN wake-up interrupt can occur only if
SLPAK=WUPIE=1.
