Reset Circuit
The microcomputer is put into a reset status by holding the RESET
pin at the “L” level for the following interval or more according to the
power source voltage and X
IN
is in stable oscillation.
After that, this reset status is released by returning the RESET pin to
the “H” level. The program starts from the address having the con-
tents of address FFFD
16
as high-order address and the contents of
address FFFC
16
as low-order address.
When V
CC
= 2.2 to 5.5 V, reset input “L” interval is 45
μ
s or more
When V
CC
= 2.4 to 5.5 V, reset input “L” interval is 35
μ
s or more
When V
CC
= 4.0 to 5.5 V, reset input “L” interval is 15
μ
s or more
In the case of f(
φ
)
≤
4 MHz, the reset input voltage must be 0.8 V or
less when the power source voltage passes 4.0 V.
In the case of f(
φ
)
≤
2 MHz, the reset input voltage must be 0.48 V or
less when the power source voltage passes 2.4 V.
In the case of f(
φ
)
≤
1 MHz, the reset input voltage must be 0.44 V or
less when the power source voltage passes 2.2 V.

Address
8-13 clock cycles
Reset address from the
vector table
1 :
A built-in ring oscillator applies about 250 kHz frequency as clock f at average of Vcc = 5 V.
2 :
The mark
“
”
means that the address is changeable depending on the previous state.
3 :
These are all internal signals except RESET.
