ADuC845 port2 SPI - digital I/O functionality

Hello, I am using the ADuC845 in a design where I will be implementing the SPI interface on the part. So for my application the SPE bit will be set to enable this functionality. I have read on page 64 of the user manual regarding the SPI functionality and multiplexing with the P2.0, P2.1, P2.2 and P2.3. I want to confirm that with SPE set that the remaining port2 pins will still have digital I/O functionality as they would if SPE was not set? It is my intent to use these non-SPI related pins in Port2 for digital I/O while at the same time using the SPI interface on the part.

thank you,
