RESET CIRCUIT
To reset the microcomputer, RESET pin must 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 must be between 2.7 V and 5.5 V,
and the oscillation must be stable), reset is released. After the re-
set 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.
