RESET CIRCUIT
To reset the microcomputer, RESET pin should be held at an "L"
level for 2
μ
s or more. Then the RESET pin is returned to an "H"
level (the power source voltage should be between 2.7 V and 5.5
V (4.0 V to 5.5 V for flash memory version), and the oscillation
should be stable), reset is released. After the reset is completed,
the program starts from the address contained in address FFFD
16
(high-order byte) and address FFFC
16
(low-order byte). Make sure
that the reset input voltage is less than 0.54 V for V
CC
of 2.7 V. For
flash memory version, make sure that the reset input voltage is
less than 0.8 V for Vcc of 4.0 V.
