Can I use pin P2.3 in ADuC845 as a general purpose pin while using SPI in
master mode?

 

Yes you can. The SS pin is only used when the part is used as an SPI slave
device.
If the part is used as a Master device then the SS functionality is not
required and P2.3 can be used according to the alternate options given in the
Datasheet...T2 input or standard digital port pin.
