Team,

my customer is using DLP-7970ABR + MSP-EXP430F5529LP for tests. They now want to design their own custom TRF7970A board.

What signals are needed to interface their custom board with the MSP-EXP430F5529LP?
Are the following signals sufficient?

SPI-CLK
SPI-MOSI
SPI-MISO
SPI-SlaveSelect

Their goal is to keep using TI-NFC-Tool for further tests and we want to make sure there are no additional signals needed for that.

I have a schematic of their custom design that I can share TI internally via email.
