Can I register an event handler more than once ?

I am using SPI MASTER example from sdk 7.2.0 with softdevice s110(using spi along with BLE). In my program I have a requirement of reconfiguring spi pins after using spi with different pins. Do I need to re-register spi event handler again after disabling spi irq??

And ask if I am not clear

Well I figure it out myself, you do not need to re-register an event handler even though you disable irq for spi.
