RESET CIRCUIT
To reset the microcomputer, RESET pin should be held at an "L"
level for 16 cycles or more of X
IN
. Then the RESET pin is returned
to an "H" level (the power source voltage should be between 2.7 V
and 5.5 V, 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.
