• Description: HCMOS Microcontroller Unit
• Manufacturer: FREESCALE [Freescale Semiconductor, Inc]

Technical Data
6.3 Stop Mode
Technical Data
The STOP instruction puts the microcontroller unit (MCU) in its lowest
power-consumption mode and has these effects on the MCU:
The STOP instruction does not affect any other registers or any
input/output (I/O) lines.
These conditions bring the MCU out of stop mode:
When the MCU exits stop mode, processing resumes after a
stabilization delay of 4064 oscillator cycles.

For More Information On This Product,
Clears TOF and RTIF, the timer interrupt flags in the timer status
and control register, removing any pending timer interrupts
Clears TOIE and RTIE, the timer interrupt enable bits in the timer
status and control register, disabling further timer interrupts
Clears the multifunction timer counter register
Sets the IRQE bit in the IRQ status and control register to enable
external interrupts
Clears the I bit in the condition code register, enabling interrupts
Stops the internal oscillator, turning off the central processor unit
(CPU) clock and the timer clock, including the computer operating
properly (COP) watchdog, and holds OSC2 at a logic 1
An external interrupt signal on the IRQ/V
transition on the IRQ/V
contents of locations $03FA and $03FB.
An external interrupt signal on a port A external interrupt pin — If
the mask option for the port A external interrupt function is
selected, a low-to-high transition on a PA3–PA0 pin loads the
program counter with the contents of locations $03FA and $03FB.
Low-voltage reset — A low-voltage detect resets the MCU and
loads the program counter with the contents of locations $03FE
and $03FF (if this mask option is selected).
External reset — A logic 0 on the RESET pin resets the MCU and
loads the program counter with the contents of locations $03FE
and $03FF.
