Driving CSB and IO_UPDATE from same signal?

As long as I obey the pin setup and pin hold timing constraints for IO_UPDATE, can I drive IO_UPDATE and CSB

with the same signal?

 

BTW, the constraints on IO_UPDATE seem fishy to me. They are specified in terms of SCLK, the SPI serial clock,

which has (in CPOL=0 mode) returned low and is inactive when the IO_UPDATE's rising edge should occur.

 

I can understand a timing specification in terms of SYSCLK, but SCLK? What am I missing?

 

Cheers,

David
