CCS/MSP430G2553: SPI multi-master

Part Number: MSP430G2553

Tool/software: Code Composer Studio

Hi team,

My customer wants to use the MSP430G2553's SPI with multi-master.

Requires master 1 to be fixed in master mode
master 2 is usually in master mode, and it switches to slave mode only when it receives a signal from master 1(GPIO pulled high).

So how to implement it? Please help.

BR,
SUSAN
