Note: 1. The capacitor connected to RESET should be of the value not greater than
0.01uF.
2. The resistor in parallel with the reset capacitor helps a lot to generate correct
reset signal and should not be removed. The drawback is an additional
current of about 1.5 uA rises.
3. The resistor in parallel with the oscillator resistor can stabilize the oscillation
clock. It can be removed if the oscillation clock is not higher than 4Mhz. Note
that the resistance should not be greater than 1000pF.
4. Connect
OE
signal of an external ROM to
RD
of ST2202 instead of GND
to prevent conflict of data bus when software error of writing to ROM occurs.
