SPI Register MSP430G2432

Other Parts Discussed in Thread: MSP430G2432, MSP430G2553

Hi,

I'm still fighting with the SPI interface. I have read in the MSP430x2xx Users Guide that there are the USCI A0 and B0 registers. I have found a example code which uses the status register and SPI receive/transmit registers of the MSP430G2553. But I just can't find the corresponding registers in the MSP430G2432. 

Can someone please help me?

Thanks

    The reason you don't find the same corresponding registers on the MSP430G2432 is because that particular device does not implement the USCI peripheral.  Instead it implements the USI.  There is a different chapter in the MSP430x2xx Users Guide for the USI peripheral.

    But how can I then send and receive more than one bytes without the buffer register?

    The 2x family users guide lists all hardware available in any member of the 2x family. It doesn't mean that every hardware module is available in every MSP of this family.
    The MSP430G2432 does not have an USCI module and therefore the example doesn't apply for this processor.

    It has, however, an USI module (with less sophisticated but still useful SPI hardware support). And there should be sample codes available for that too.
