The microcontroller unit (MCU) can enter these low-power standby
modes:
Freescale Semiconductor, Inc.
For More Information On This Product,
Stop mode — The STOP instruction puts the MCU in its lowest
power-consumption mode.
Wait mode — The WAIT instruction puts the MCU in an
intermediate power-consumption mode.
Halt mode — Halt mode is identical to wait mode, except that an
oscillator stabilization delay of 1 to 4064 internal clock cycles
occurs when the MCU exits halt mode. The stop-to-wait
conversion bit, SWAIT, in the mask option register, enables halt
mode.
