MSCAN Controller
18.8 Low Power Modes
Technical Data
338
The msCAN12 has three modes with reduced power consumption
compared to normal mode. 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 WAI and STOP instructions put the MCU in low power consumption
stand-by modes.
and CPU modes. A particular combination of modes is entered for the
given settings of the bits CSWAI, SLPAK, and SFTRES. For all modes,
an msCAN wake-up interrupt can occur only if SLPAK=WUPIE=1. While
the CPU is in Wait Mode, the msCAN12 can be operated in Normal
Mode and emit interrupts (registers can be accessed via background
debug mode).
