interfacing cc2541

hi,
I want to interface SPI memory chip-AT45DB021E (www.adestotech.com/.../doc8789.pdf) with cc2541 for extra storage purpose.
configuration is as shown below:-
memory side           cc2541 side
SI                        -         P1_5
SO                      -         P1_4 
SCK                   -          P1_3
CS_N                 -         P1_2

I already interface (UART) msp430 with cc2541 by simply adding serialInterface.c/h file to simpleBLEBroadcaster code (because i also want advertising on cc2541) as suggested in link:-processors.wiki.ti.com/.../SimpleBLEPeripheral_SerialInterface.

msp430 side       cc2541 Side
P3.4 (TX)               P0_7 (RX)
P3.5 (RX)               P0_6 (TX)

in UART code where should i define these pin configaration?

can you give me hint on spi memory chip interfacing (SPI interfacing).

Thank u in advance.
