PRELIMINARY
Notice: This is not a final specification.
Some parametric limits are subject to change.
Reset Circuit
The microcomputer is put into a reset status by holding the RESET
pin at the “L” level for 2 μs or more when the power source voltage is
2.2 to 5.5 V 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.
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.
