RESET CIRCUIT
When the oscillation of a quartz-crystal oscillator or a ceramic reso-
nator is stable and the power source voltage is 5 V ± 10 %, hold the
______
RESET pin at LOW for 2 s or more, then return is to HIGH. Then, as
shown in Figure 75, reset is released and the program starts from
the address formed by using the content of address FFFF16 as the
high-order address and the content of the address FFFE16 as the
low-order address. The internal state of microcomputer at reset are
shown in Figure 75.
An example of the reset circuit is shown in Figure 74.
The reset input voltage must be kept 0.6 V or less until the power
source voltage surpasses 4.5 V.

Notes 1 :
:
f(XIN) and f(
φ) are in the relation : f(XIN) = 2f (φ).
2
A question mark (?) indicates an undefined state that
depends on the previous state.
3
Immediately after a reset, timer 3 and timer 4 are
connected by hardware. At this time, “FF16” is set
in timer 3 and “0716” is set to timer 4. Timer 3 counts down
with f(XIN)/16, and reset state is released by the timer 4
overflow signal.
