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.
