hi my design need to have one SPI master and one SPI slave on MSP430F5152 , so i design USCI_A0 be the SPI master and USCI_B0 be the SPI slave. and my SPI Slave need to be 4 wire type, but the UCB0STE and UCA0CLK share the same pin, that means if i using USCI_A0, then my USCI_B0 can't use the UCB0STE be the /CS function, am i right? if i'm right, how to achieve one SPI master and one 4-wire SPI Slave on MSP430F5152 ?
