5. Reset
If the RST pin remains at low level for more than a minimum of 3 instruction cycles (15 fundamental
clocks) when the power supply voltage is within the operating voltage range and oscillation is stable, the
system is reset and the internal states are initialized.
When the RST pin is set to high level, the reset operation is cancelled and execution of the program at
address 000H begins.
