The HD6432695 is
the HD6432633.
The pins
corresponding to
OSC1 and OSC2 in
the HD64F2633 are
NC pins in the
HD6432695.
Properties
of multi-
use pins
(pins 34
and 35)
Output of pins 34 and 35 is normally NMOS push-pull output, but is NMOS open-drain output
when the IIC bus drive function is selected.
No IIC function.
Pins 34 and 35
output is CMOS
output.
