MSP430F5438A: Can I interface an external programming flash?

Part Number: MSP430F5438A
Other Parts Discussed in Thread: UNIFLASH

Tool/software:

Greetings,

1. Can I interface an external SPI programming flash with this microcontroller? 
If yes, do you have any recommended ones?

2. Additionally, can I develop all the programs needed on CCS? or I'll need any other IDE to work with?

Thanks!
