For More Information On This Product,
Stops the internal oscillator, the CPU clock, and the internal clock,
turning off the capture/compare timer, the COP watchdog, the
SIOP, and the ADC
Clears the I bit in the condition code register, enabling external
interrupts
Clears the ICIE, OCIE, and TOIE bits in the timer control register,
disabling further timer interrupts
An external interrupt signal on the IRQ pin or a high-to-low
transition on the IRQ pin loads the program counter with the
contents of locations $1FFA and $1FFB. The timer resumes
counting from the last value before the STOP instruction.
