MC13213 & SMAC

I am using one of the SMAC demo applications to test my custom board with MC13213. It looks like reading from any of the modem registers (SPI singular transaction) gives back 0x0000!?! The writing should work, because I am able to change the CLKO from the default after modem reset 32.78....KHz to 8MHZ (this only can be done by successful write to the 0x0A register). Of cause I can suspect my hardware, but then why the writing works?
Any ideas....
Thank you!
