RESET CIRCUIT
To reset the microcomputer, 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 2.8 V and 5.5
V, and XIN oscillation is stable), reset is released. In order to give
the XIN clock time to stabilize, internal operation does not begin
until after about 4000 XIN clock cycles (256 cycles of f(XIN)/16) are
completed. After the reset is completed, the program starts from
the address contained in address FFFD16 (high-order) and ad-
dress FFFC16 (low-order). Make sure that the reset input voltage
is 0.5 V or less for 2.8 V of VCC.

f(XIN) and f(
φ) are in the relationship : f(XIN) = 8f(φ)
A question mark (?) indicates an undefined state that depends on the previous state.
