RESET CIRCUIT
To reset the microcomputer, RESET pin must be held at an “L”
level for 20 cycles or more of X
to an “H” level (the power source voltage must be between 2.7 V
and 5.5 V, and the oscillation must be stable), reset is released.
After the reset is completed, the program starts from the address
contained in address FFFD
