Reset
The MCU is reset by inputting a high-level voltage to the RESET pin. At power-on or when stop mode is
cancelled, RESET must be high for at least one t
RC
to enable the oscillator to stabilize. During operation,
RESET must be high for at least two instruction cycles.
Initial values after MCU reset are shown in table 1.
