Reset Circuit
To reset the microcomputer, the RESET pin should be held at an
“L” level for 2
s or more. Then the RESET pin is returned to an “H”
level (the power source voltage should be between 3.0 V and 5.5
V, and between 4.0 V and 5.5 V for extended operating tempera-
ture version), reset is released. Internal operation does not begin
until after 8 to 13 XIN clock cycles are completed. After the reset is
completed, the program starts from the address contained in ad-
dress FFFD16 (high-order byte) and address FFFC16 (low-order
byte).
Make sure that the reset input voltage is less than 0.6 V for VCC of
3.0 V (Extended operating temperature version: the reset input
voltage is less than 0.8 V for VCC of 4.0 V).

Note. ! : Undefined
V : The initial values of CM1 are determined by the level at the
CNVSS pin.
The contents of all other registers and RAM are undefined
after a reset, so they must be initialized by software.
