     * |[11:8]  |SUSPITV   |Suspend Interval (Master Only)
     * |        |          |This bit field provides the configurable suspend interval between two successive transmit/receive transaction in a transfer
     * |        |          |The definition of the suspend interval is the interval between the last clock edge of the preceding transaction word and the first clock edge of the following transaction word

     * |        |          |Example:

     * |        |          |In Slave mode, this bit field is used for Slave time-out period

     * |        |          |Example: Assume SLVTOCNT is 0x0A and TMCNTSRC (USPI_BRGEN[5]) is 1, it means the time-out event will occur if the state of SPI bus clock pin is not changed more than (10+1) periods of fDIV_CLK.
