Reset
The MCU can be reset by setting the RESET pin high or by setting the
STOPC
pin low*. When power is
first applied, or when clearing subactive mode, watch mode, or stop mode, the RESET input must be held
for at least t
RC
to assure that the oscillation stabilization time (t
RC
) condition is fulfilled.
Similarly, the
STOPC
pin input must held for at least t
RC
when clearing stop mode with a
STOPC
pin input
to assure that the oscillator stabilizes.
In all other cases, the MCU is reset by a RESET input that is held for at least two instruction execution
cycles.
Table 1 lists the section of the MCU that are initialized by a reset and the initial values.
Note: * The
STOPC
pin reset is only effective in stop mode.
