Reset Circuit
The microcomputer is put into a reset status by holding the RE-
SET pin at the “L” level for 2
s or more when the power source
voltage is 4.5 to 5.5 V and XIN 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
contents of address FFFD16 as high-order address and the con-
tents of address FFFC16 as low-order address.
In the case of f(
φ) ≤ 8 MHz, the reset input voltage must be 0.9 V
or less when the power source voltage passes 4.5 V.

vector table
1 : A built-in ring oscillator applies about RING2 MHz,
φ250 kHz frequency clock
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.
