Resistor
to Ground
3) Not Connected
Not recommended for CHMOS
designs. Causes approximately
16 mA of additional current flow
through the XTAL1 pin on UPI-
C42 and approximately 11 mA of
additional current through XTAL1
on the UPI-L42.
Recommended configuration for
designs which will use both
NMOS and CHMOS parts. This
configuration limits the additional
current through the XTAL1 pin to
approximately 1 mA, while
maintaining compatibility with the
NMOS device.
Low power configuration
recommended for CHMOS only
designs to provide lowest
possible power consumption.
This configuration will not work
with the NMOS device.
