Problem with writing certain SCU registers

Using a LPC4357 I am trying to configure P9_3 to have MCOA0 function.
If I write to the configuration register 0x40086000+0x49C it seems to have no effect I read back all zeros, but if I do the same for another pin (0x40086494) the change takes effect and I read back the correct value.
What can cause this behavior?
